The replies here arguing we should publish it all are wild in the worst kind of first-order thinking way.
Itâs a census: it just asks questions.
If you start publishing and weaponizing the data against people with various attributes, theyâll just lie or not answer. And then you are left with worse than nothing: bad data people try to act on.
The US Government is the entity that weaponizes the data. The most obvious example is the Census Bureau compiling lists of people of Japanese descent to imprison during WWII. That's just the most obvious one that I know of without looking up more.
The real push for this now is to form lists of people to disenfranchise.
Turnout in the past few elections was already extraordinarily high. Clearly this isnât the answer. And neither is protesting, considering that 4 of the 5 largest demonstrations in US history happened in the past 10 years and achieved nothing.
You also need the option to vote for "less-bad" people. Where I am now, my vote doesn't matter, even if it means the "less-bad" people win with no competition (as opposed to where I moved from where things were skewed the opposite way).
> Turnout in the past few elections was already extraordinarily high.
In a sense, this in itself is the issue. It's long-term _worse_ to vote for the "lesser of two serious evils". This extreme "long-term pain for short-term gain" attitude is what's gotten the US to where it is. If in 2016 of 2024 even 20% of the dems would've stayed home or voted third party, the DNC's continuous forcing of awful corpocrats with zero charisma would've become completely untenable and Trump would've been limited to one term. Yet instead they were rewarded for it, so you'll see Newsom get the candidacy and presidency in 2028 (if 2028 even happens at this point), and then in 2032 you'll get something like Hegseth or Thiel winning and it's all over.
There is an answer: relentlessly vote, but only for candidates who are actually slightly decent - including third-party - and otherwise stay at home. "Relentlessly" means "at every level", including locally from the very bottom, all the way up.
The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb because a vote for someone who loses isn't a wasted vote. It shows the others that there's a voter there who can be convinced if catered to, if they select a better candidate. The powers that be have done a fantastic job of brainwashing the entire population of the myth that anyone who _doesn't_ go out and vote for either major candidate is a morally bankrupt person, because it directly benefits them.
The reply to this will be "well it's too late for that now!". It's wrong because the alternative doesn't help you one bit. You're just wishing for a miracle, that in 4 years something happens, kicking the can down the road making things worse long term. And that's actually what's got you here.
It's a symptom of the terminal disease which has infected all layers of American society and has gotten it to where it's at: short-termism. Everyone just looks at the next quarter, the next election. China's ascendency is 1:1 tied to doing the exact opposite. Some smartypants will now point "but zero Covid", great you found a potential exception, now look at the other 90% of policy.
Every time I've explained this I've gotten instantly downvoted without a single reply making an argument against it, because it's too painful for people to admit that they've been part of the road to where the US is at. And again, short-termism: rather feel the short-term tiny dopamine hit by slamming that downvote button than thinking about it. Let's see if this happens again.
> The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb because a vote for someone who loses isn't a wasted vote.
Yes, but with a caveat, if you had a strong preference between the top two actually-likely-to-win candidates (assuming the third party wasn't competitive), it's at least not voting the most in your interests for the outcome. Which is why we really need approval voting, so we can actually vote for the candidates we like, rather than needing to "strategically" hold our noses.
But I agree with the rest of it, if none of the candidates represent you, the third-party vote at least allows you to send a signal of "I vote, but you need to make me want to vote for you, and this is what I want".
> 2024 [...] the DNC's continuous forcing of awful corpocrats with zero charisma would've become completely untenable and Trump would've been limited to one term.
You mean the 2024 election cycle where incumbents all around the globe were beaten because the economic situation was strongly anti-incumbent? Are you positing that the US election was somehow a unique outlier and solely down to Harris being the Democrat candidate? Even though a swing of 115k votes would have handed the presidency to Harris instead?
It sounds like you have a particular issue with the 2016 and 2024 elections and I'm wondering if there's something in common that might explain it...
> Every time I've explained this I've gotten instantly downvoted without a single reply making an argument against it,
Ok I'll break it down for you.
> If in 2016 of 2024 even 20% of the dems would've stayed home or voted third party
Parties cater to their bases, and putting yourself out there as an unreliable voting bloc is exactly how you get your demands ignored.
> The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb
It's not incredibly dumb, it's simple mathematical reality. This doesn't change unless the first past the post system changes. Why do you think the GOP backs the Green Party?
You are saying the candidates are forced on us by someone else. But that's just wrong, we choose the candidates. Anybody can run, there is no secret cabal that decides who can run and who can't.
Didn't happen last year when Kamila was selected by the leaders.
But in normal years candidates are successful because of the amount of money they can raise. The more they can raise the more brainwashing ads they can buy. The non so secret cabal is the donor class.
Anyone can run? You must meet requirements on age and how long you have lived in the US. You must pay fees and provide signatures for each state. If doing it through a party you have to meet their rules.
Cost to get on most states ballots at a basic level is a million. You could do it for free if you dont want to appear on any ballots.
The ideal is that anyone can run, but it's not that easy to just start an independent campaign that has a decent chance of winning. Local races are the most realistic "anyone can run" arena, but once you need a lot of travel and logistics in a large region, you either need a lot of your own resources or the support of an existing large political organization.
You do know the former head of the DNC was forced to retire after the leaked emails outed her, and basically all of the top of the DNC, extensively conspiring against Sanders in favor of Clinton? [1] You're right the cabal isn't secret - it's literally the DNC, and who they want to win is who will win, one way or the other. Just reading over that source - it's insane how blatant these people can be:
"In May 2016, MSNBC's Mika Brzezinski accused the DNC of bias against the Sanders campaign and called on Wasserman Schultz to step down. Wasserman Schultz was upset at the negative media coverage of her actions, and she emailed the political director of NBC News, Chuck Todd, that such coverage of her "must stop". Describing the coverage as the "LAST straw", she ordered the DNC's communications director to call MSNBC president Phil Griffin to demand an apology from Brzezinski."
> Every time I've explained this I've gotten instantly downvoted
Because it's dumb. People don't want to hear dumb ideas, or take the time to try and convince someone that would spend however long it took to type that, apparently multiple times, without realizing it. Throwing away votes will never be the reasonable thing to do. I know you don't want to hear that, because it's too painful for you to admit there's no simple answer.
> The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb because a vote for someone who loses isn't a wasted vote. It shows the others that there's a voter there who can be convinced if catered to, if they select a better candidate.
Tried that in 2000, voting for Nader as a protest vote against Clinton/Gore third way neoliberalism. I did that in a state where the electoral votes for Dems were 100% safe. Still just got blamed for Bush and there was zero self-reflection on the part of the Democratic Party.
...
I would urge everyone to stop fixating on the Presidential vote as the only fight to win and everything being win/lose based on that outcome. If the Congressional Progressive Caucus in the House exceeds 50% of Democrats in the House, then we can start thinking about a world where e.g. AOC might be the speaker of the House rather than Nancy Pelosi.
> It's a symptom of the terminal disease which has infected all layers of American society and has gotten it to where it's at: short-termism. Everyone just looks at the next quarter, the next election.
Yeah, and the Office of the President is 4-8 years and is just more short-termism, along with individualism / cult of personality / CEO-leadership. If you want to make lasting change in the DNC, start by flipping more and more House seats to progressive from neoliberal.
I'm pretty sure they didn't think this through in a comprehensive fashion.
Because making it esy to find all the rich people just seems like a very bad idea given the direction things are going.
When it was broad, the only thing you could do was locate, say, large minority groups. Blacks and latinos for instance. And even that led to problems. I can't imagine what will happen when we can drill down and tease out immigrants from citizens. Gay from straight. Rich from well to do. And so on.
Do you really need the census to find people of specific demographics in 2026? Pretty sure I can go up to anyone in any state and ask where all the Puerto Ricans live and get an answer (in many cases I'm sure I'll get stared at like I'm crazy, but that's still an answer). I know because my parents moved to predominantly Hispanic parts of Florida before fully settling down where we landed, I REALLY doubt they stopped to pull up census data to decide where to find Hispanics / Puerto Ricans in Florida. You can talk to any local of any area and figure out which areas are a specific nationality without census data.
Yeah okay fair, I was about to post a knee jerk reaction, but it's well known that the US government can obtain higher quality data by just simply buying it from the public market.
They haven't done a single thing without malicious intent. Go back and find whatever else you've defended in the past, and look at the results instead of the stated reason/goal for doing them. They won't match. They'll be opposites. You'll rationalize or shift blame, of course. But maybe this time, something decent will get through.
Cell tower data, credit bureau integration, social media scraping, palantir, smart home device surveillance, DNA database exploitation, facial recognition networks, tax, payroll, passport, visa, medicare/medicaid, immigrations and customs databases and many more...
The census is a historical relic used to jerrymander congressional seats, and that's about it.
Census data provides a reliable source to build off of, which makes joining between data sets more reliable. A lot of what you're talking about would be partial prints of an identity that have to be joined up with others to give reliable data.
Eg
> Cell tower data
That's just going to get you a subscriber and device ID, unless you're talking about going deep packet inspection and parsing the contents of the packets. You could, but that's a lot of effort to get something the census can hand you for free.
> credit bureau integration
Notoriously unreliable and identities for the purpose of credit get stolen constantly. The easiest way to clean that is against known-good info, like the census.
> social media scraping
Half the profiles are fake, also not reliable data unless you clean it up. Again, census data makes it very easy to cut out profiles that don't match a real person.
> tax, payroll
These are probably fairly reliable, although they usually won't tell you about a person's demographics.
> passport, visa, medicare/medicaid, immigrations and customs databases
There's an enormous part of the population that won't appear in these at all. The huge part of the country that's "working poor" but not poor enough for Medicaid probably aren't traveling internationally. I wouldn't be surprised if half the country doesn't appear in any of these.
The census has value in that it contains a huge depth of information, is tied with your identity, citizens are compelled by law to answer so even the privacy folks have to respond and lying on it is a crime (enforcement is probably non-existent, though).
I'm sure that can all be reconstructed to some level of accuracy given sufficient effort, but that's a lot harder and requires a ton more coordination than "SELECT * FROM census_data WHERE ..."
I have to agree. I'd like Census data to be private, but the cat is out of the bag.
I'm all for keeping all of this data private. But to think it isn't already available is a bit 'head in sand'. Maybe put laws in place for 'general' privacy across all data, before getting too inflamed about Census in particular.
Even at a quick glance this doesn't make any sense. The census is literally how they get the data. Where else would it come from? Drones? Every computer being hacked Michael Bay style?
I don't work in this industry so I don't know their secret sauce, but I would be surprised if census data is not used as a baseline for what they're selling. It doesn't make sense to not want to use it if your next best sources are relying on everyone in the household having an app that sells their location to your network constantly. I see outdated data about me on the public versions of these sites all the time, so I know they don't have omniscience.
> Title 13 provides the following protections to individuals and businesses:

> Census Bureau employees are sworn to protect confidentiality. People sworn to uphold Title 13 are legally required to maintain the confidentiality of your data.

Violating the law is a serious federal crime. Anyone who violates this law will face severe penalties, including a federal prison sentence of up to five years, a fine of up to $250,000, or both.
The easy solution is to just reduce the resolution and scope of the data to the degree it is absolutely necessary. The census exists to inform representation decisions. All other concerns are addons. You can have all the data on the county or voting district level and strip data as you increase your resolution, to the point you only keep population number at the neighborhood, block level.
Knowing the racial, ethnic and socioeconomic background of the residents of a single building block is only useful to discriminate against them.
You first gather the data while people don't know or care. Then you weaponize it later. It happened at least once not long ago in another country, seems not overreaction to be concerned about it
It happened a year ago in this country, with IRS sharing data with ICE (breaking a longstanding policy of keeping taxpayer data private within the government).
If this is a Nazi reference, Census data was used to send people to concentration camps here during the same era. Less awful than death camps, at least.
Extremists or in general any fraction willing to engage in systematic discrimination, harassment, terrorizing or similar love highly detailed non anonymized census data.
Why?
Because it gives them the perfect layout for which areas to harass (areas likely to yield), which to brutalize (areas unlikely to yield or from especially "hated" people), which to best not touch which (areas with too much influence/money or likely to contain hidden sympathizers), which to systematically take apart through other means like building a highway through them (e.g. "hated" communities to strong/connected to brutalize). etc. etc.
All of this has a lot of history weather it's from right extremists like fascists or left extremists(1).
At which point the question is, if the data you collect is that abuseable. Should you even collect it? Is it even really needed?
(1): Like actual left extremists, the a lot of US sources have the habit to label people as left extremists which by EU standards sometimes aren't even left (but centrist) and very far away from extremism...
Any use to identify where government resources are best used, will have people thinking they should have gotten more and would have if they'd answered differently. Ie, that their answers were "weaponized" against them.
I guess the way to optimize is to find an equilibrium between an extreme of specificity and an extreme of vagueness that's still actionable from a high-level policy perspective.
Something about this conversation is fundamentally broken if there's no space to iterate towards optimization and instead it's just swinging between maximalist extremes.
The Harper government actively worked on destroying the efficacy of the Canadian census, to make it more difficult for subsequent governments to make data-driven decisions.
In addition to the obvious goal of making it easier to identify and target homosexuals, trans people, minorities, immigrants, it's quite possible that destroying future governments' ability to make good decisions is one of the objectives of the Republican party. Stop voting for the face-eating leopard party, already.
For all the very clever people pointing out that this is nothing new, I have two responses.
1. Your cell company may track your location, and your credit rating agencies know how many nose hairs you have, but they doesn't always (or even usually) have the deeply personal information you're supposed to put down in a census.
2. Enough of a change in degree is a change in kind. If you disagree, remember that Imperial Russia had the Okhrana and sent over a million Sybiraks - prisoners and exiles - to Siberia, and then the fucking CHEKA and the NKVD and then the (kinder, softer, slightly less outright murderous) KGB went ahead to send 18 million people into the GULAG system, and outright murdered half a million to a million. This was all the same, right? No difference?
There's a pretty good chance the Elon Musk, plus Russia and China have had more-orless unrestricted access to American's data since the DOGE dismantling of US government. Plus, by intentionally removing security and accountability mechanisms it makes it impossible to accurately determine how bad the damage actually was.
You canât completely trust what people say anyway. There are stated preferences and observed preferences in economics but it applies to other areas of life.
The entity most capable of weaponizing demographic data is the government itself. If people werenât previously providing false information to the census, Iâm skeptical that this change is what will push people over the edge.
Congress passed laws that blocked the federal government from fusing data across departments for this specific reason. the admin decided to ignore those, and a friendly congress is deciding to not act on that.
You really, really don't want a government who can build a unified profile on you in that way.
Isn't the issue here the lack of accountability? Maybe an unpopular opinion, but I don't think its a foregone conclusion that governments are fundamentally corrupt. Ours certainly is and we have a very weak constitution which makes it worse, but that's the US. I think better constitutions are possible, but we have to stop treating it like a sacred document and be practical.
> I don't think its a foregone conclusion that governments are fundamentally corrupt
There's a question of what you mean. Is it, can they be corrupt? have they been corrupt? are they currently corrupt (because of the previous, or incidentally)?
Plato thought Democracy was corrupt and it's the least inherently corrupt system I know of. I would say they are fundamentally corrupt. The best you can do is try to limit it with a document (like the US Constitution) and setting up a multi-branch power structure capable of adversarial action. As you point out, the US does not have that and it's showing.
I "enumerated" for the last census. Trust in my community was already not high* and I had lots of interesting encounters. I really believed the rather invasive data I was collecting with a friendly face would be used and handled responsibly. I feel for the poor souls that'll sign up to go door to door for 2030 now that the firewalls against weaponizing and monetizing all of our sensitive government data has been torn down, and even more for those that will volunteer information that can hurt them.
The comments that this rather expensive endeavour should just be about getting a head count are also amusing to me. The data collected was such an important baseline of common understanding, and this will not be a good thing for its future quality. I've grown very jaded now seeing all the things taken for granted in this country and lost or degraded recently with a whimper.
*: To be fair, they sent me specifically to places that didn't respond, so I was naturally led to believe that everyone in my region hated the government, ignored bizzarrely threatening fliers, or had recently moved and had no knowledge of the inhabitants (if any) during the census period.
Coming from a certain european country, you never know what answer on the census might get you into trouble.
"What is your religious affiliation". Seems perfectly innocuous, but turned out to be retroactively fatal if your answer could be attributed to you by a certain foreign occupier in the 1940s .
Europeâs next persecution is obviously going to be migrants. So surely any institution caught collecting, processing, or retaining information about citizenship, nationality, work authorization, etc. has been destroyed by the data privacy regulators, right?
Say you get your way, and, for fear of Mark Carney rolling the tanks in and taking over North America, the US stops collecting any data on its citizens. How is the IRS supposed to know how much tax to expect from you? How is SNAP supposed to determine your eligibility? How is unemployment supposed to know if you're ripping them off or not? Data privacy is a real concern, but you need PII to run government services effectively. Running a state without collecting PII is like running a hospital without collecting any.
> How is the IRS supposed to know how much tax to expect from you? How is SNAP supposed to determine your eligibility? How is unemployment supposed to know if you're ripping them off or not?
How does knowing your religious affiliation help them with any of this?
France used to make plenty of lists. We loved lists. Lists are good. Jews lists? Sure, it's maybe useful one day when we want to do something.
Boy were the Germans happy to find these.
The American obsession with asking for people their perceived origins (AAPI, AA, Latino, ...) is more than weird: it's downright dangerous. Don't fucking ask these questions, and never, ever write it down, especially not with names.
Thankfully, now they can just buy it from data brokers and let Palantir target, so that makes life easier for them
It actually does. Religious affinity can absolutely be useful for longer trend studies, and census data is usually of much, much higher quality than other random sample studies.
Pretty sad, in my opinion. In my ideal the state should have visibility into the shape of the people present so that we can make good decisions about our combined organization. I think weâre making a mistake we will come to regret by intentionally damaging our data collection infrastructure.
I think a large amount of the USâs success is the result of good institutions handling granular data. Policies can be adjusted to match outcomes more rapidly than otherwise.
I understand why people decide to diminish all state capacity - they feel that governments are populated by their opponents who will use state capacity against them. But as our relative strength wanes, our ability to overcome these forces of inertia does as well. And then our governments become less capable and eventually life starts getting worse.
We donât need house-level data immediately (except perhaps in order to place census blocks within their appropriate congressional district etc). But there are aggregation units above which we should be using as good information as we possibly could be.
TFA lays out why things don't work that way. If you erode trust in the privacy of census responses, an awful lot of folks will have to start lying on their census
Whatever you do, there is a level of trust that is assumed when census takes place. The trust that this data is then not identified in a way that could be targeted for scams, frauds, and other such evils. But in NY, house sale records are made public but much to the detriment, many mortgage companies fake a bill for payment.
Differential privacy is absolutely necessary, and the social scientists being unable to reconstruct the data at an individual level is intended. A macroscopic description is rather enough for most purposes, and anything more is asking for a surveillance state.
> But in NY, house sale records are made public but much to the detriment, many mortgage companies fake a bill for payment.
That frankly sounds more like a failure of enforcement, on top of a failure of the construction of the financial system. Here in Germany, it is absolutely not a common thing that mortgages or the banks holding them get sold like a hot potato towards some other sucker, and thus such a letter would cause immediate suspicion.
Ban it from the dataset, add it to the analysis. You can choose your own flavor of noise.
I don't know what the political undertones are here, but at some level you need to have actual ground truth, including "this person/household declined".
Publishing raw data though? That seems like shooting yourself in the foot from a national security perspective, not to mention all the other reasons not to do it.
> Differential privacy makes this trade-off explicit, and thus impossible to ignore. Maybe banning it is a way of pretending that the problem doesn't exist, in the hope that it will go away?
Or it's saying that one of these conflicting goals is more valuable than the other, and so shouldn't be sacrificed for it.
Can anyone explain to me the previous state and why it was desirable? I admittedly do not understand why people are getting riled up. I am not being difficult. I really don't understand the original state and the changed state here.
So "differential privacy" pretty much sounds like someone gets to modify the results of a census and how it gets modified is entirely up to their discretion.
Seems like something that could be abused to achieve political objectives.
i have such a hard time reconciling stuff like this:
> The census bureau decided to adopt differential privacy for the 2020 Census
and:
> The consequences will be dire for utility or for privacy, and possibly both. It's hard to understate this point: future statistical releases will either be useless compared to past ones, or they will be incredibly unsafe
so we took the census for centuries before this point, and it was âok.â and for the last census only we added some privacy items. but if we remove just one of those filters, we are in âdireâ circumstances? but there were no privacy features before. so weâre actually still much better off than we were for hundreds of years before this.
this makes it feel like an emotional overblown problem
Believe it or not, mathematical techniques and computational power have increased in the past hundreds of years, not to mention the digitization of everything.
Privacy issues that werenât possible before due to cost are now pennies to exploit. Also keep in mind as it points out people were using census data to drive gerrymandering efforts, so these attacks are real and have been going on for a long time.
Computers and improvements in data science/machine learning are basically the entire explanation. A LOT of the techniques that we use today to de-anonymize data require computation power not previously available. Even when doable, resources limited scale. Source: statistics degree
(Also, linkage. There are more data sources to cross reference now with the internet and social media and web tracking and hacks - the record footprint of Americans even as recently as the 70s and 80s was dramatically lower!)
> but there were no privacy features before. so weâre actually still much better off than we were for hundreds of years before this.
One notable thing we have today that we didn't have 100 years ago is a computer. Before, you could reasonably assume that recreating individual records wasn't feasible, at least not on a large scale. You can't assume that now. A 4 digit password was safe for hundreds of years, but it would be a security lability today for the same reason.
As the article clearly states, privacy features have been in the census since 1990. It is just that the previously used privacy feature was not very strong and could be defeated. So it was replaced by a stronger feature in 1920. Before 1990 the census. 1990 was when personal computers were being popularized and the computing power available to individuals exploded and so then it was possible to use computers to separate out individual information from the data the census publishes. So the issue came up then.
And a lot of countries have things like national IDs that, rightly or wrongly, given things like RealID and passports, that a lot of Americans just don't like on principle.
Sure, in Europe we don't because we already have databases of all citizens, also recording attributes like race, skin color, religious affiliation or political leaning in a database is highly illegal, both for the government and for private use.
Many countries effectively have a live registry of where people live, updated to within a few weeks.
A census isnât needed because they can do something like
SELECT a., b.
FROM registry a
INNER JOIN national_id b
ON a.nat_id_num = b.id_num
WHERE timeframe = 2026-01-01
I think it should be noted that there was a lot of dissatisfaction from users of the census data as far as I know. So it's not been banned just for politicals sake or because they hate privacy... Some people I talked to in the privacy field even called the whole thing a total disaster and weren't shy to put blame on John Abowd who apparently pushed this through despite a lot of internal opposition and concerns. Not sure if that's true, but what is definitely true is that the way the data was released produced serious issues downstream as most researchers and statisticians that ingested the data weren't prepared for receiving noisy data values. Differential privacy was applied in a way such that many invariants that data users cared about weren't preserved, which was expected as it's not possible as you can't preserve all invariants and at the same time add meaningful noise to the data. The thing is, with such a differentially private data release you need to adapt all of the downstream analyses to take into account the exact mechanism the data was altered in. And since the census bureau used a very intricate mechanism that didn't just add Laplace noise to data values but instead relied on a multi-stage process that preserved some invariants but not others it was very difficult to even write routines to account for the changes being made to the data. They essentially asked of every data user to rewrite their whole analysis pipeline based on the exact disclosure mechanism that contained a large number of bespoke choices regarding which data invariants to preserve and basically produced a mix of noisy, synthesized data that was just really hard to reason about. I don't even know if there even would've been a way to do this better, but the fact is that not every small county or school district has top-tier statisticians at hand that can just read a whole monograph on differentially private synthesized census data and then hotpatch their existing analysis systems to work with that data.
I was a big fan of differential privacy but now I think it might be doing more harm than good, as I haven't seen a single case where it was applied successfully in a problem where it actually mattered, and it contributed strongly to discrediting and preventing a lot of work on other anonymization techniques as it was deemed the only way to preserve privacy by the research community, so showing up with enhancements to k-anonymity or any other noise mechanism not rooted in it was a sure way to get ridiculed and ignored. And it's just not a practical mechanism, even when it works for a single disclosure you always end up having to blow up the privacy budget to a ridiculous amount in order to keep disclosing statistics as otherwise you would for almost all real-world data run out of budget after a few publications.
So, for me it's a technique that works in the areas where it doesn't really matter (publishing highly aggregated statistics that pose almost zero privacy risk even without differential privacy) and doesn't work in other areas where it would actually matter (publishing fine-grained data about individuals or small groups). There are some niche use cases but in my view the privacy community has really overblown the importance of differential privacy by portraying it as the only way to reliably anonymize data.
BTW the German census bureau has an interesting approach to anonymization which they use for several decades already and so far I haven't heard of any cases of successful de-anonymization of the data, maybe the US bureau should have a look at that for their own needs.
Of course there will be dissatisfaction from users of the data. Anyone that wants to use census data will prefer less privacy in the data. And anytime privacy is enforced the data becomes less useful. It would be certainly very convenient for both advertisers and gerrymandering political consultants to have detailed data on every citizen.
As the article says anytime you want to enforce privacy, the data becomes somewhat less useful, there is just no way around that.
The point of rights is that we have them and that they should not be trampled upon when they become slightly inconvenient to someone in power.
Are you sure about that? You are saying that differentially private census data couldn't be used for gerrymeandering and advertisement while non differentially private data could? Hard to believe, I'm not an advertisement or gerrymeandering expert but I would assume people running ads or cutting up districts are mostly interested in aggregate statistics i.e. they won't care about single households? And I would assume they can rely on voter files, party databases etc... And to the contrary there are reports [1] that indicate differential privacy actually makes gerrymeandering analysis more difficult or impossible. So, not really an argument for differential privacy, discriminatory action can be equally well taken based on differentially private data as the government cares about groups not individuals and groups aren't protected by differential privacy. It seems people really fundamentally misunderstand what this technique can achieve and what it won't do.
> serious issues downstream as most researchers and statisticians that ingested the data weren't prepared for receiving noisy data values
They weren't prepared for data that was obviously noisy. The data has always been inherently inaccurate, and folks just chose to ignore that previously
No, there are dozens of articles discussing the mechanism and explaining the impact it had in different areas e.g. [1,2,3]. And the release mechanism wasn't just "add noise", far from it, you may read the original paper [4] to see how intricate it was, anyone wanting to make real use the resulting data would have needed to understand that approach in detail to work with the resulting data. The report of the national academies [3] is probably the most comprehensive analysis of the mechanism and the complications it introduced, so writing "it has always been inherently inaccurate" is just wrong, this new mechanism was way worse than just introducing unbiased sampling noise.
The dueling political demands of accuracy and privacy are simply incompatible at some level. After reading this, maybe Hanlon's Razor isn't the right standard. Besides malice and stupidity, there is impossibility. Some problems just aren't solvable under certain constraints. I don't envy the statisticians tasked with finding a politically palatable solution to a math problem.
But the strength of differential privacy is that you can now make this tradeoff explicit and quantify it. I always liked it because it offers a mathematical solution to a policy problem, but then of course it's up to us to decide what parameters and tradeoff to choose. Also, some data might just not get published at all if the privacy implications are too problematic, so differential privacy might buy you more signal!
Yeah, the main issue with differential privacy is that you need competent government officials making decisions who understand math beyond a high school level.
There's a ton of information in the US that is accessible to various degrees--especially through the the deep web much less background investigations. Unless you're a wealthy person who can set up various levels of trusts you can't really hide them.
You can of course disagree about what what should actually be part of a transparent public record. (Though I suspect a lot of people post-date what was generally available in a "phone book.")
I really have to take the anti-noise side here. I get why it's a hard problem, and I get why the Census Bureau thought this was a neat solution. But I'm imagining an accountant stepping through a similar chain of logic:
* I want to accurately report the finances of our company to the best of my ability.
* But that report would allow people to reconstruct private data about the terms of our contracts with various counterparties. I'd really like to avoid that, there's no rule that says we're supposed to release that data. In fact some of those contracts probably came with nondisclosure agreements!
* So here's what I'm going to do. I'm going to calculate our results to the best of my ability, and then I'm going to add random values to them and report only the randomized ones. Any reconstruction people try to do will be wrong because of the randomness.
* If the SEC says "no, you need to report your actual numbers", I will explain to them that there's no such thing as an actual number because all data is noisy.
This is a gift to reactionary gerrymandering and voting restriction efforts, along with things like yesterday's FBI raid of an Ohio voting rights organization.
Representative Beatty serves her own interests and her involvement Kennedy Center naming was just more of the same performative politics she routinely engages in. She's on the verge of being an octogenarian and missed a number of key votes, like the bill that cut funding to NPR, PBS, and other govt. programs. Kudos to her for working to remove Trump's name from the Kennedy Center but she needs to go.
Frankly i see no reason to keep this data private. They should simply publish a full dataset of the census, with no such data coarsening/differential privacy/ etc...
Fundamentally this is public data. If it's to dangerous to make public, it's too dangerous to collect, and people should be aware of exactly what it is.
There are very few things that the state has data on that should not be made public. Census data is simply not one of those things.
publishing should be the default for any data, and to keep it unpublished should require substantially good reasons that impact the country as a whole. Frankly, if it isn't detailed national defence plans, i struggle to see any data that should not be public.
The biggest challenge with running a census is getting people to trust you enough to answer your questions.
A lot of census questions are sensitive. The ACS covers topics like citizenship status, disabilities, income, SNAP assistance, languages spoken at home.
If you want accurate information about the people who live in your country you need the census process to feel as safe for people to respond to as possible.
Are you saying the census shouldn't collect any data that people wouldn't be comfortable publishing? Because that's a recipe for a census that is far less useful for helping the country make useful decisions.
> Are you saying the census shouldn't collect any data that people wouldn't be comfortable publishing? Because that's a recipe for a census that is far less useful for helping the country make useful decisions.
I'll say that. The state representatives should provide congress and the president any data needed to inform policy decisions about the people they represent. And as others have pointed out, other departments and agencies (such as the IRS) have most of the rest of the data required to make policy decisions.
Except for gerrymandering purposes, I fail to see why income, party affiliations, etc., is useful for the purpose the census was created for.
>And as others have pointed out, other departments and agencies (such as the IRS) have most of the rest of the data required to make policy decisions.
There are laws in place forbidding government agencies from merging together datasets.
The last thing people should support is creating of profiles of individuals by combining data from different government agencies. This is why the census is so important as a data collection mechanism.
> There are laws in place forbidding government agencies from merging together datasets.
This is an excellent point. In my opinion, such laws are a good idea. Most of the time, policy decisions should not require IRS data. (Or other personal data.)
But to get around such laws, the government asks citizens to provide that data a second time (in the census). And sometimes it's asked yet again on other forms. This seems to defeat the purpose of those laws.
I can see that federal disaster aid might need to know if some area needs more or less aid, depending on the wealth of the area receiving aid. If aid is given to individuals, the have a need to know the individuals' income.
When there is a reasonable need to know, I would prefer the government use the much more accurate IRS data, rather than ask for people's income multiple times. The laws preventing merging federal datasets could be rethought, given what is now known about preserving privacy mathematically. I would like to see specific exemptions made, with the provided data properly anonymized to preserve privacy while serving the legitimate purpose for which the data was requested. The use of such data should require a request to congress for it.
This seemsâs like an issue created by congress. the constitution only requires a headcount by state. Maybe they should use another mechanism to collect demographic data. Since the concern is not about representation, but allocation, tax returns seem like an obvious alternative and they are already private and collected at a much more granular level.
The census isn't for helping the country make any decisions other than determining the number of representatives and apportionment of taxes. It should not be collecting any data that isn't necessary for that.
> The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.
The key thing you're missing is "in such Manner as they shall by Law direct".
Congress has passed a whole bunch of laws that attach additional responsibilities to the census for the purpose of supporting government decisions.
I'd like to know when they stopped publishing census data. I have used it for genealogical purposes to track ancestors: you can see exactly who was living in which house, how they are related, and what their ages are (I found that women in my family often reported, both on the census and marriage documents, being younger than they actually were). I don't think I've seen data from after 1950, though.
I don't understand why the census would include SNAP data or income: surely the government already has that information. I have never doubted that the IRS knows my income better than I do. Maybe better use of existing datasets could restrict the census to less invasive questions.
They haven't stopped but they don't happen immediately.
Detailed census records are published 72 years after they were collected; the last release (of 1950 census data) came out in 2022; the next one should be published in 2032.
The Census Bureau is a lot more than the 10-year Census, and it already makes very extensive use of IRS data and other administrative sources. Virtually everything that is published using these sources uses either differential privacy or other privacy protection methods that are prohibited by the order. I'm guessing that a lot of those pieces of data are just going to be put on hold until the order is reversed or weakened. A number of things might have to go away permanently, as there's almost certainly no way to protect privacy in them without some kind of noise infusion.
TBH I don't think the people who wrote this knew how much collateral impact it would have.
Replying to the ACS with accurate information is required by law, so they don't actually need to rely on people feeling safe to get answers.
I don't trust the Census Bureau with my data, so if this is as "dangerous" as the author and some people here seem to think, they shouldn't be collecting it in the first place.
There's not many cases of enforcement. Non-response is taken about as seriously as the RobinsonâPatman act. I think the Census Bureau is very reliant on people thinking there will be enforcement, however, which is why the materials they send all have a threatening aura. I don't know about the ACS, but for the decennial census I often felt like my job as an enumerator was just to bother people until they'd answer. The case would keep being recycled until we got at least (IIRC) a head count.
They can certainly enforce that you answer the survey. But it's very difficult to enforce a requirement that people answer questions accurately, particularly when they perceive that doing so will expose them to danger.
I don't get what danger is being referenced here that exists only if the data is released to the public (in aggregate)?
The government is the primary and arguably only source of the danger, and they already have most of the data whether you answer the ACS correctly or not.
1. People give the information to the government under the expectation that this data is to be kept private or used in such a way that individual targeting is made impossible, you break that expectation and people will lie or won't give you this data.
2. Without noise injection it's rather simple to do statistical attacks to reverse engineer individual entities.
3. This data is and has already been used in the past to undermine democratic systems by targeting and disenfranchising minorities, as well as gerrymandering the US to hell.
4. "Too dangerous to make public, too dangerous to collect" - this is a false dichotomy. To govern effectively you need sensitive data, but it should be collected and used in a way that's safe for the individuals.
5. Macro level aggregates don't need individual exposure, that's why noise, anonymization and statistical functions are fine.
That's a good default position, and I think should be our starting point.
But the devil is in the details. If we don't want advertisers constructing semi-complete profiles from simple web interactions then why would we publish 330 million census questionnaires for their use?
So do you believe that individual income should be public? Or do you believe that the government should not take income into account for taxation or distribution of benefits?
Then dox yourself right now with your previous census answers and PII. There are several obvious reasons to keep the data private, all you have to do is use your brain.
But why is the census asking about those attrbutes at all. The Constitution requires a count. That's it. A number. We don't need to know the rest of it, or if we do, it should be surveyed separately with voluntary participation.
> We don't need to know the rest of it, or if we do, it should be surveyed separately with voluntary participation.
But we do. A detailed census is essential for making good policy. For example, knowing the age and distribution of children across the country helps local and state governments decide where to put the next school or children's hospital. The federal govt. allocates funds for education and daycare accordingly.
The census is the best and most important measure of govt. policy. Taking it away would leave everyone worse off.
The risks of abuse are too high and historically proven to happen eventually. There are many other ways to determine where schools and hospitals are needed, such as aggregate enrollment and admission statistics.
Local school districts know where they need more or fewer schools. This sort of thing isn't any business or responsibilty of the federal government at all.
Census participation is not voluntary. Failure to provide complete or accurate data is, in theory, punishable by a fine. Last census, I intentionally provided incomplete data on the web form, which resulted in a person with a clipboard and some stern questions showing up at my door.
The replies here arguing we should publish it all are wild in the worst kind of first-order thinking way.
Itâs a census: it just asks questions.
If you start publishing and weaponizing the data against people with various attributes, theyâll just lie or not answer. And then you are left with worse than nothing: bad data people try to act on.
The US Government is the entity that weaponizes the data. The most obvious example is the Census Bureau compiling lists of people of Japanese descent to imprison during WWII. That's just the most obvious one that I know of without looking up more.
The real push for this now is to form lists of people to disenfranchise.
Remember âleftist â and transgender activists are terrorists now.

Voting and getting everyone you know to vote
And civically engaging. Less than a fifth of voters regularly contact their electeds.
The people in power now are doing everything they can to make that as hard as possible by any means necessary. Good luck.
No, they are doing everything they can to ensure that only the people who are legally allowed to vote are the ones voting.
Turnout in the past few elections was already extraordinarily high. Clearly this isnât the answer. And neither is protesting, considering that 4 of the 5 largest demonstrations in US history happened in the past 10 years and achieved nothing.
Well right... you also need to vote for the correct ("less-bad") people and get your friends to do the same.
Voting for the worse people makes things worse.
You also need the option to vote for "less-bad" people. Where I am now, my vote doesn't matter, even if it means the "less-bad" people win with no competition (as opposed to where I moved from where things were skewed the opposite way).
> Turnout in the past few elections was already extraordinarily high.
In a sense, this in itself is the issue. It's long-term _worse_ to vote for the "lesser of two serious evils". This extreme "long-term pain for short-term gain" attitude is what's gotten the US to where it is. If in 2016 of 2024 even 20% of the dems would've stayed home or voted third party, the DNC's continuous forcing of awful corpocrats with zero charisma would've become completely untenable and Trump would've been limited to one term. Yet instead they were rewarded for it, so you'll see Newsom get the candidacy and presidency in 2028 (if 2028 even happens at this point), and then in 2032 you'll get something like Hegseth or Thiel winning and it's all over.
There is an answer: relentlessly vote, but only for candidates who are actually slightly decent - including third-party - and otherwise stay at home. "Relentlessly" means "at every level", including locally from the very bottom, all the way up.
The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb because a vote for someone who loses isn't a wasted vote. It shows the others that there's a voter there who can be convinced if catered to, if they select a better candidate. The powers that be have done a fantastic job of brainwashing the entire population of the myth that anyone who _doesn't_ go out and vote for either major candidate is a morally bankrupt person, because it directly benefits them.
The reply to this will be "well it's too late for that now!". It's wrong because the alternative doesn't help you one bit. You're just wishing for a miracle, that in 4 years something happens, kicking the can down the road making things worse long term. And that's actually what's got you here.
It's a symptom of the terminal disease which has infected all layers of American society and has gotten it to where it's at: short-termism. Everyone just looks at the next quarter, the next election. China's ascendency is 1:1 tied to doing the exact opposite. Some smartypants will now point "but zero Covid", great you found a potential exception, now look at the other 90% of policy.
Every time I've explained this I've gotten instantly downvoted without a single reply making an argument against it, because it's too painful for people to admit that they've been part of the road to where the US is at. And again, short-termism: rather feel the short-term tiny dopamine hit by slamming that downvote button than thinking about it. Let's see if this happens again.
> The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb because a vote for someone who loses isn't a wasted vote.
Yes, but with a caveat, if you had a strong preference between the top two actually-likely-to-win candidates (assuming the third party wasn't competitive), it's at least not voting the most in your interests for the outcome. Which is why we really need approval voting, so we can actually vote for the candidates we like, rather than needing to "strategically" hold our noses.
But I agree with the rest of it, if none of the candidates represent you, the third-party vote at least allows you to send a signal of "I vote, but you need to make me want to vote for you, and this is what I want".
> 2024 [...] the DNC's continuous forcing of awful corpocrats with zero charisma would've become completely untenable and Trump would've been limited to one term.
You mean the 2024 election cycle where incumbents all around the globe were beaten because the economic situation was strongly anti-incumbent? Are you positing that the US election was somehow a unique outlier and solely down to Harris being the Democrat candidate? Even though a swing of 115k votes would have handed the presidency to Harris instead?
It sounds like you have a particular issue with the 2016 and 2024 elections and I'm wondering if there's something in common that might explain it...
> Every time I've explained this I've gotten instantly downvoted without a single reply making an argument against it,
Ok I'll break it down for you.
> If in 2016 of 2024 even 20% of the dems would've stayed home or voted third party
Parties cater to their bases, and putting yourself out there as an unreliable voting bloc is exactly how you get your demands ignored.
> The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb
It's not incredibly dumb, it's simple mathematical reality. This doesn't change unless the first past the post system changes. Why do you think the GOP backs the Green Party?
You are saying the candidates are forced on us by someone else. But that's just wrong, we choose the candidates. Anybody can run, there is no secret cabal that decides who can run and who can't.
Didn't happen last year when Kamila was selected by the leaders.
But in normal years candidates are successful because of the amount of money they can raise. The more they can raise the more brainwashing ads they can buy. The non so secret cabal is the donor class.
Anyone can run? You must meet requirements on age and how long you have lived in the US. You must pay fees and provide signatures for each state. If doing it through a party you have to meet their rules.
Cost to get on most states ballots at a basic level is a million. You could do it for free if you dont want to appear on any ballots.
The ideal is that anyone can run, but it's not that easy to just start an independent campaign that has a decent chance of winning. Local races are the most realistic "anyone can run" arena, but once you need a lot of travel and logistics in a large region, you either need a lot of your own resources or the support of an existing large political organization.
You do know the former head of the DNC was forced to retire after the leaked emails outed her, and basically all of the top of the DNC, extensively conspiring against Sanders in favor of Clinton? [1] You're right the cabal isn't secret - it's literally the DNC, and who they want to win is who will win, one way or the other. Just reading over that source - it's insane how blatant these people can be:
"In May 2016, MSNBC's Mika Brzezinski accused the DNC of bias against the Sanders campaign and called on Wasserman Schultz to step down. Wasserman Schultz was upset at the negative media coverage of her actions, and she emailed the political director of NBC News, Chuck Todd, that such coverage of her "must stop". Describing the coverage as the "LAST straw", she ordered the DNC's communications director to call MSNBC president Phil Griffin to demand an apology from Brzezinski."

> Every time I've explained this I've gotten instantly downvoted
Because it's dumb. People don't want to hear dumb ideas, or take the time to try and convince someone that would spend however long it took to type that, apparently multiple times, without realizing it. Throwing away votes will never be the reasonable thing to do. I know you don't want to hear that, because it's too painful for you to admit there's no simple answer.
> The whole idea of "third-party voting is a complete waste in the US" is incredibly dumb because a vote for someone who loses isn't a wasted vote. It shows the others that there's a voter there who can be convinced if catered to, if they select a better candidate.
Tried that in 2000, voting for Nader as a protest vote against Clinton/Gore third way neoliberalism. I did that in a state where the electoral votes for Dems were 100% safe. Still just got blamed for Bush and there was zero self-reflection on the part of the Democratic Party.
...
I would urge everyone to stop fixating on the Presidential vote as the only fight to win and everything being win/lose based on that outcome. If the Congressional Progressive Caucus in the House exceeds 50% of Democrats in the House, then we can start thinking about a world where e.g. AOC might be the speaker of the House rather than Nancy Pelosi.
> It's a symptom of the terminal disease which has infected all layers of American society and has gotten it to where it's at: short-termism. Everyone just looks at the next quarter, the next election.
Yeah, and the Office of the President is 4-8 years and is just more short-termism, along with individualism / cult of personality / CEO-leadership. If you want to make lasting change in the DNC, start by flipping more and more House seats to progressive from neoliberal.
I'm pretty sure they didn't think this through in a comprehensive fashion.
Because making it esy to find all the rich people just seems like a very bad idea given the direction things are going.
When it was broad, the only thing you could do was locate, say, large minority groups. Blacks and latinos for instance. And even that led to problems. I can't imagine what will happen when we can drill down and tease out immigrants from citizens. Gay from straight. Rich from well to do. And so on.
Do you really need the census to find people of specific demographics in 2026? Pretty sure I can go up to anyone in any state and ask where all the Puerto Ricans live and get an answer (in many cases I'm sure I'll get stared at like I'm crazy, but that's still an answer). I know because my parents moved to predominantly Hispanic parts of Florida before fully settling down where we landed, I REALLY doubt they stopped to pull up census data to decide where to find Hispanics / Puerto Ricans in Florida. You can talk to any local of any area and figure out which areas are a specific nationality without census data.
Does anyone actually believe this crap?
You think the census is what the government would use to mass identify and imprison people, not the NSA database(s)?
You think homeland security, or the FBI, or any other alphabet agency doesn't already have access to a giant list of people?
Think about what meta knows about everyone, or Google. You do realize that the US gov has read access to their core databases right?
"The census" has absolutely no bearing on any of that which you're worried about.
It's just shocking the level of ignorance that gets upvoted in the comments here now.
You think they wouldn't use every tool available to then, including the census data?
Yeah okay fair, I was about to post a knee jerk reaction, but it's well known that the US government can obtain higher quality data by just simply buying it from the public market.
> Does anyone actually believe this crap?
> You think the census is what the government would use to mass identify and imprison people, not the NSA database(s)?
I think, and history shows, they would use the tools at their disposal.
Example: https://stateline.org/2026/01/20/ice-is-using-medicaid-data-...
They haven't done a single thing without malicious intent. Go back and find whatever else you've defended in the past, and look at the results instead of the stated reason/goal for doing them. They won't match. They'll be opposites. You'll rationalize or shift blame, of course. But maybe this time, something decent will get through.
I'm not sure why your comment is grayed out.
Cell tower data, credit bureau integration, social media scraping, palantir, smart home device surveillance, DNA database exploitation, facial recognition networks, tax, payroll, passport, visa, medicare/medicaid, immigrations and customs databases and many more...
The census is a historical relic used to jerrymander congressional seats, and that's about it.
Census data provides a reliable source to build off of, which makes joining between data sets more reliable. A lot of what you're talking about would be partial prints of an identity that have to be joined up with others to give reliable data.
Eg
> Cell tower data
That's just going to get you a subscriber and device ID, unless you're talking about going deep packet inspection and parsing the contents of the packets. You could, but that's a lot of effort to get something the census can hand you for free.
> credit bureau integration
Notoriously unreliable and identities for the purpose of credit get stolen constantly. The easiest way to clean that is against known-good info, like the census.
> social media scraping
Half the profiles are fake, also not reliable data unless you clean it up. Again, census data makes it very easy to cut out profiles that don't match a real person.
> tax, payroll
These are probably fairly reliable, although they usually won't tell you about a person's demographics.
> passport, visa, medicare/medicaid, immigrations and customs databases
There's an enormous part of the population that won't appear in these at all. The huge part of the country that's "working poor" but not poor enough for Medicaid probably aren't traveling internationally. I wouldn't be surprised if half the country doesn't appear in any of these.
The census has value in that it contains a huge depth of information, is tied with your identity, citizens are compelled by law to answer so even the privacy folks have to respond and lying on it is a crime (enforcement is probably non-existent, though).
I'm sure that can all be reconstructed to some level of accuracy given sufficient effort, but that's a lot harder and requires a ton more coordination than "SELECT * FROM census_data WHERE ..."
I have to agree. I'd like Census data to be private, but the cat is out of the bag.
I'm all for keeping all of this data private. But to think it isn't already available is a bit 'head in sand'. Maybe put laws in place for 'general' privacy across all data, before getting too inflamed about Census in particular.
Even at a quick glance this doesn't make any sense. The census is literally how they get the data. Where else would it come from? Drones? Every computer being hacked Michael Bay style?
Data mining companies?
Donât forget thereâs an entire industry that exists solely for this purpose.
I don't work in this industry so I don't know their secret sauce, but I would be surprised if census data is not used as a baseline for what they're selling. It doesn't make sense to not want to use it if your next best sources are relying on everyone in the household having an app that sells their location to your network constantly. I see outdated data about me on the public versions of these sites all the time, so I know they don't have omniscience.
It is probably not a baseline for what they're selling.

The easy solution is to just reduce the resolution and scope of the data to the degree it is absolutely necessary. The census exists to inform representation decisions. All other concerns are addons. You can have all the data on the county or voting district level and strip data as you increase your resolution, to the point you only keep population number at the neighborhood, block level.
Knowing the racial, ethnic and socioeconomic background of the residents of a single building block is only useful to discriminate against them.
There are plenty of other uses - knowing where to build stores to serve your target market, predicting possible pandemic vulnerabilities, etc.
You first gather the data while people don't know or care. Then you weaponize it later. It happened at least once not long ago in another country, seems not overreaction to be concerned about it
It happened a year ago in this country, with IRS sharing data with ICE (breaking a longstanding policy of keeping taxpayer data private within the government).
If this is a Nazi reference, Census data was used to send people to concentration camps here during the same era. Less awful than death camps, at least.
Yes.
Extremists or in general any fraction willing to engage in systematic discrimination, harassment, terrorizing or similar love highly detailed non anonymized census data.
Why?
Because it gives them the perfect layout for which areas to harass (areas likely to yield), which to brutalize (areas unlikely to yield or from especially "hated" people), which to best not touch which (areas with too much influence/money or likely to contain hidden sympathizers), which to systematically take apart through other means like building a highway through them (e.g. "hated" communities to strong/connected to brutalize). etc. etc.
All of this has a lot of history weather it's from right extremists like fascists or left extremists(1).
At which point the question is, if the data you collect is that abuseable. Should you even collect it? Is it even really needed?
(1): Like actual left extremists, the a lot of US sources have the habit to label people as left extremists which by EU standards sometimes aren't even left (but centrist) and very far away from extremism...
Any use to identify where government resources are best used, will have people thinking they should have gotten more and would have if they'd answered differently. Ie, that their answers were "weaponized" against them.
I guess the way to optimize is to find an equilibrium between an extreme of specificity and an extreme of vagueness that's still actionable from a high-level policy perspective.
Something about this conversation is fundamentally broken if there's no space to iterate towards optimization and instead it's just swinging between maximalist extremes.
This administration does ... not ... care ... about ... facts.
> theyâll just lie or not answer
The Harper government actively worked on destroying the efficacy of the Canadian census, to make it more difficult for subsequent governments to make data-driven decisions.
In addition to the obvious goal of making it easier to identify and target homosexuals, trans people, minorities, immigrants, it's quite possible that destroying future governments' ability to make good decisions is one of the objectives of the Republican party. Stop voting for the face-eating leopard party, already.
For all the very clever people pointing out that this is nothing new, I have two responses.
1. Your cell company may track your location, and your credit rating agencies know how many nose hairs you have, but they doesn't always (or even usually) have the deeply personal information you're supposed to put down in a census.
2. Enough of a change in degree is a change in kind. If you disagree, remember that Imperial Russia had the Okhrana and sent over a million Sybiraks - prisoners and exiles - to Siberia, and then the fucking CHEKA and the NKVD and then the (kinder, softer, slightly less outright murderous) KGB went ahead to send 18 million people into the GULAG system, and outright murdered half a million to a million. This was all the same, right? No difference?
There's a pretty good chance the Elon Musk, plus Russia and China have had more-orless unrestricted access to American's data since the DOGE dismantling of US government. Plus, by intentionally removing security and accountability mechanisms it makes it impossible to accurately determine how bad the damage actually was.
have you not been paying attention for 10 years? At the top of the rotting snakehead they know all this, they arn't arguing in good faith.
You canât completely trust what people say anyway. There are stated preferences and observed preferences in economics but it applies to other areas of life.
>Itâs a census: it just asks questions.
Thats what dutch and french bureaucrats thought until 1940.
The entity most capable of weaponizing demographic data is the government itself. If people werenât previously providing false information to the census, Iâm skeptical that this change is what will push people over the edge.
Congress passed laws that blocked the federal government from fusing data across departments for this specific reason. the admin decided to ignore those, and a friendly congress is deciding to not act on that.
You really, really don't want a government who can build a unified profile on you in that way.
Isn't the issue here the lack of accountability? Maybe an unpopular opinion, but I don't think its a foregone conclusion that governments are fundamentally corrupt. Ours certainly is and we have a very weak constitution which makes it worse, but that's the US. I think better constitutions are possible, but we have to stop treating it like a sacred document and be practical.
> I don't think its a foregone conclusion that governments are fundamentally corrupt
There's a question of what you mean. Is it, can they be corrupt? have they been corrupt? are they currently corrupt (because of the previous, or incidentally)?
Plato thought Democracy was corrupt and it's the least inherently corrupt system I know of. I would say they are fundamentally corrupt. The best you can do is try to limit it with a document (like the US Constitution) and setting up a multi-branch power structure capable of adversarial action. As you point out, the US does not have that and it's showing.
I "enumerated" for the last census. Trust in my community was already not high* and I had lots of interesting encounters. I really believed the rather invasive data I was collecting with a friendly face would be used and handled responsibly. I feel for the poor souls that'll sign up to go door to door for 2030 now that the firewalls against weaponizing and monetizing all of our sensitive government data has been torn down, and even more for those that will volunteer information that can hurt them.
The comments that this rather expensive endeavour should just be about getting a head count are also amusing to me. The data collected was such an important baseline of common understanding, and this will not be a good thing for its future quality. I've grown very jaded now seeing all the things taken for granted in this country and lost or degraded recently with a whimper.
*: To be fair, they sent me specifically to places that didn't respond, so I was naturally led to believe that everyone in my region hated the government, ignored bizzarrely threatening fliers, or had recently moved and had no knowledge of the inhabitants (if any) during the census period.
Coming from a certain european country, you never know what answer on the census might get you into trouble.
"What is your religious affiliation". Seems perfectly innocuous, but turned out to be retroactively fatal if your answer could be attributed to you by a certain foreign occupier in the 1940s .
Europeâs next persecution is obviously going to be migrants. So surely any institution caught collecting, processing, or retaining information about citizenship, nationality, work authorization, etc. has been destroyed by the data privacy regulators, right?
Surely any such foreign occupier would just demand the unredacted data?
Exactly why a government may refrain from collecting such data, as it is not even relevant in any kind of policy decision.
That's where you hope people like Rene Carmille are around. S
Yes, which is why the government shouldn't have this data at all in the first place.
Say you get your way, and, for fear of Mark Carney rolling the tanks in and taking over North America, the US stops collecting any data on its citizens. How is the IRS supposed to know how much tax to expect from you? How is SNAP supposed to determine your eligibility? How is unemployment supposed to know if you're ripping them off or not? Data privacy is a real concern, but you need PII to run government services effectively. Running a state without collecting PII is like running a hospital without collecting any.
> How is the IRS supposed to know how much tax to expect from you? How is SNAP supposed to determine your eligibility? How is unemployment supposed to know if you're ripping them off or not?
How does knowing your religious affiliation help them with any of this?
"Collecting data" is what helps them.
They should follow the principle of least privilege. Why not use differential privacy?
France used to make plenty of lists. We loved lists. Lists are good. Jews lists? Sure, it's maybe useful one day when we want to do something.
Boy were the Germans happy to find these.
The American obsession with asking for people their perceived origins (AAPI, AA, Latino, ...) is more than weird: it's downright dangerous. Don't fucking ask these questions, and never, ever write it down, especially not with names.
Thankfully, now they can just buy it from data brokers and let Palantir target, so that makes life easier for them
"What is your religious affiliation" makes absolutely no sense in a census exercise. IMO.
The U.S. Census Bureau collects tons of data unrelated to the decennial counting for Congressional apportionment.
https://www.census.gov/programs-surveys.html
The American Community Survey is the most well-known, as it replaced the âlong formâ sampling that had been an extension to the Census.
Unless youâre a government explicitly and openly aligned with Christian nationalists.
The point might be going over my head⌠why does it make no sense?
why it makes sense? please try to answer. what action of the gov would change based on that data?
then, make it so your answer is more valid than if they asked what you usually have for breakfast.
i guarantee you more gov actions can be positively impacted by the breakfast question than the religion one.
the ONLY use for religious data is to get it for free for campaigns.
It actually does. Religious affinity can absolutely be useful for longer trend studies, and census data is usually of much, much higher quality than other random sample studies.
Asking about your religion on the census is against the law in the US:
no person shall be compelled to disclose information relative to his religious beliefs or to membership in a religious body.
https://www.congress.gov/94/statute/STATUTE-90/STATUTE-90-Pg...
Religion is just an example. Don't dwell on it.
> compelled
Doesn't that mean they can ask that question with an option for "rather not disclose"?
Pretty sad, in my opinion. In my ideal the state should have visibility into the shape of the people present so that we can make good decisions about our combined organization. I think weâre making a mistake we will come to regret by intentionally damaging our data collection infrastructure.
I think a large amount of the USâs success is the result of good institutions handling granular data. Policies can be adjusted to match outcomes more rapidly than otherwise.
I understand why people decide to diminish all state capacity - they feel that governments are populated by their opponents who will use state capacity against them. But as our relative strength wanes, our ability to overcome these forces of inertia does as well. And then our governments become less capable and eventually life starts getting worse.
We donât need house-level data immediately (except perhaps in order to place census blocks within their appropriate congressional district etc). But there are aggregation units above which we should be using as good information as we possibly could be.
> I think weâre making a mistake we will come to regret by intentionally damaging our data collection infrastructure.
Intentionally damaging infrastructure is the recurring theme of this administration.
Iâd be more interested in giving my state detailed info, letting them run programs. The country can have aggregate data.
But this article is about a decision to damage the census less. If you value an accurate census, you should be celebrating!
TFA lays out why things don't work that way. If you erode trust in the privacy of census responses, an awful lot of folks will have to start lying on their census
Whatever you do, there is a level of trust that is assumed when census takes place. The trust that this data is then not identified in a way that could be targeted for scams, frauds, and other such evils. But in NY, house sale records are made public but much to the detriment, many mortgage companies fake a bill for payment.
Differential privacy is absolutely necessary, and the social scientists being unable to reconstruct the data at an individual level is intended. A macroscopic description is rather enough for most purposes, and anything more is asking for a surveillance state.
> But in NY, house sale records are made public but much to the detriment, many mortgage companies fake a bill for payment.
That frankly sounds more like a failure of enforcement, on top of a failure of the construction of the financial system. Here in Germany, it is absolutely not a common thing that mortgages or the banks holding them get sold like a hot potato towards some other sucker, and thus such a letter would cause immediate suspicion.
Ban it from the dataset, add it to the analysis. You can choose your own flavor of noise.
I don't know what the political undertones are here, but at some level you need to have actual ground truth, including "this person/household declined".
Publishing raw data though? That seems like shooting yourself in the foot from a national security perspective, not to mention all the other reasons not to do it.
> Ban it from the dataset, add it to the analysis. You can choose your own flavor of noise.
It is introduced in the public data, not the secret data.
> Differential privacy makes this trade-off explicit, and thus impossible to ignore. Maybe banning it is a way of pretending that the problem doesn't exist, in the hope that it will go away?
Or it's saying that one of these conflicting goals is more valuable than the other, and so shouldn't be sacrificed for it.
Can anyone explain to me the previous state and why it was desirable? I admittedly do not understand why people are getting riled up. I am not being difficult. I really don't understand the original state and the changed state here.
Read up here for example: https://www2.census.gov/library/publications/decennial/2020/...
So "differential privacy" pretty much sounds like someone gets to modify the results of a census and how it gets modified is entirely up to their discretion.
Seems like something that could be abused to achieve political objectives.
i have such a hard time reconciling stuff like this:
> The census bureau decided to adopt differential privacy for the 2020 Census
and:
> The consequences will be dire for utility or for privacy, and possibly both. It's hard to understate this point: future statistical releases will either be useless compared to past ones, or they will be incredibly unsafe
so we took the census for centuries before this point, and it was âok.â and for the last census only we added some privacy items. but if we remove just one of those filters, we are in âdireâ circumstances? but there were no privacy features before. so weâre actually still much better off than we were for hundreds of years before this.
this makes it feel like an emotional overblown problem
Believe it or not, mathematical techniques and computational power have increased in the past hundreds of years, not to mention the digitization of everything.
Privacy issues that werenât possible before due to cost are now pennies to exploit. Also keep in mind as it points out people were using census data to drive gerrymandering efforts, so these attacks are real and have been going on for a long time.
Computers and improvements in data science/machine learning are basically the entire explanation. A LOT of the techniques that we use today to de-anonymize data require computation power not previously available. Even when doable, resources limited scale. Source: statistics degree
(Also, linkage. There are more data sources to cross reference now with the internet and social media and web tracking and hacks - the record footprint of Americans even as recently as the 70s and 80s was dramatically lower!)
> but there were no privacy features before. so weâre actually still much better off than we were for hundreds of years before this.
One notable thing we have today that we didn't have 100 years ago is a computer. Before, you could reasonably assume that recreating individual records wasn't feasible, at least not on a large scale. You can't assume that now. A 4 digit password was safe for hundreds of years, but it would be a security lability today for the same reason.
As the article clearly states, privacy features have been in the census since 1990. It is just that the previously used privacy feature was not very strong and could be defeated. So it was replaced by a stronger feature in 1920. Before 1990 the census. 1990 was when personal computers were being popularized and the computing power available to individuals exploded and so then it was possible to use computers to separate out individual information from the data the census publishes. So the issue came up then.
No it is not an overblown problem.
For decades we were encrypting our communications with rsa, surely nothing is wrong with it?
There is nothing wrong with it, and RSA is still commonly used. In fact, RSA is better against quantum computers compared to ECC.
The concerns here, like most concerns about privacy, are hyperbolic hypothetical hypochondria, until theyâre not.
https://www.npr.org/2026/06/12/nx-s1-5855734/census-bureau-d...
I guess this could be implemented externally.
Eg via some app that instructs respondents to enter a specific answer in a pseudorandomly chosen question.
Of course security would be another question.
Census data is extremely powerful. It's why some states lost house seats and why some gained house seats.
It must therefore be maximally transparent. Do you want president Trump or palantir to decide on the "noise infusion" algorithm?
The fines for non-compliance are low enough to remain silent.
Do. The American Census Survey (randomly-selected long-form questionairre) is dangerously overinvasive.
The better to sell the data, all your privates are belong to us.
Can anyone share how other countries handle this?
A lot of countries are really bad at running their census. https://asteriskmag.com/issues/11/why-governments-cant-count
And a lot of countries have things like national IDs that, rightly or wrongly, given things like RealID and passports, that a lot of Americans just don't like on principle.
Sure, in Europe we don't because we already have databases of all citizens, also recording attributes like race, skin color, religious affiliation or political leaning in a database is highly illegal, both for the government and for private use.
Wait, are you saying Europe doesn't have censuses?
Many countries effectively have a live registry of where people live, updated to within a few weeks. A census isnât needed because they can do something like
SELECT a., b. FROM registry a INNER JOIN national_id b ON a.nat_id_num = b.id_num WHERE timeframe = 2026-01-01
I think it should be noted that there was a lot of dissatisfaction from users of the census data as far as I know. So it's not been banned just for politicals sake or because they hate privacy... Some people I talked to in the privacy field even called the whole thing a total disaster and weren't shy to put blame on John Abowd who apparently pushed this through despite a lot of internal opposition and concerns. Not sure if that's true, but what is definitely true is that the way the data was released produced serious issues downstream as most researchers and statisticians that ingested the data weren't prepared for receiving noisy data values. Differential privacy was applied in a way such that many invariants that data users cared about weren't preserved, which was expected as it's not possible as you can't preserve all invariants and at the same time add meaningful noise to the data. The thing is, with such a differentially private data release you need to adapt all of the downstream analyses to take into account the exact mechanism the data was altered in. And since the census bureau used a very intricate mechanism that didn't just add Laplace noise to data values but instead relied on a multi-stage process that preserved some invariants but not others it was very difficult to even write routines to account for the changes being made to the data. They essentially asked of every data user to rewrite their whole analysis pipeline based on the exact disclosure mechanism that contained a large number of bespoke choices regarding which data invariants to preserve and basically produced a mix of noisy, synthesized data that was just really hard to reason about. I don't even know if there even would've been a way to do this better, but the fact is that not every small county or school district has top-tier statisticians at hand that can just read a whole monograph on differentially private synthesized census data and then hotpatch their existing analysis systems to work with that data.
I was a big fan of differential privacy but now I think it might be doing more harm than good, as I haven't seen a single case where it was applied successfully in a problem where it actually mattered, and it contributed strongly to discrediting and preventing a lot of work on other anonymization techniques as it was deemed the only way to preserve privacy by the research community, so showing up with enhancements to k-anonymity or any other noise mechanism not rooted in it was a sure way to get ridiculed and ignored. And it's just not a practical mechanism, even when it works for a single disclosure you always end up having to blow up the privacy budget to a ridiculous amount in order to keep disclosing statistics as otherwise you would for almost all real-world data run out of budget after a few publications.
So, for me it's a technique that works in the areas where it doesn't really matter (publishing highly aggregated statistics that pose almost zero privacy risk even without differential privacy) and doesn't work in other areas where it would actually matter (publishing fine-grained data about individuals or small groups). There are some niche use cases but in my view the privacy community has really overblown the importance of differential privacy by portraying it as the only way to reliably anonymize data.
BTW the German census bureau has an interesting approach to anonymization which they use for several decades already and so far I haven't heard of any cases of successful de-anonymization of the data, maybe the US bureau should have a look at that for their own needs.
Of course there will be dissatisfaction from users of the data. Anyone that wants to use census data will prefer less privacy in the data. And anytime privacy is enforced the data becomes less useful. It would be certainly very convenient for both advertisers and gerrymandering political consultants to have detailed data on every citizen.
As the article says anytime you want to enforce privacy, the data becomes somewhat less useful, there is just no way around that.
The point of rights is that we have them and that they should not be trampled upon when they become slightly inconvenient to someone in power.
Are you sure about that? You are saying that differentially private census data couldn't be used for gerrymeandering and advertisement while non differentially private data could? Hard to believe, I'm not an advertisement or gerrymeandering expert but I would assume people running ads or cutting up districts are mostly interested in aggregate statistics i.e. they won't care about single households? And I would assume they can rely on voter files, party databases etc... And to the contrary there are reports [1] that indicate differential privacy actually makes gerrymeandering analysis more difficult or impossible. So, not really an argument for differential privacy, discriminatory action can be equally well taken based on differentially private data as the government cares about groups not individuals and groups aren't protected by differential privacy. It seems people really fundamentally misunderstand what this technique can achieve and what it won't do.

> serious issues downstream as most researchers and statisticians that ingested the data weren't prepared for receiving noisy data values
They weren't prepared for data that was obviously noisy. The data has always been inherently inaccurate, and folks just chose to ignore that previously
No, there are dozens of articles discussing the mechanism and explaining the impact it had in different areas e.g. [1,2,3]. And the release mechanism wasn't just "add noise", far from it, you may read the original paper [4] to see how intricate it was, anyone wanting to make real use the resulting data would have needed to understand that approach in detail to work with the resulting data. The report of the national academies [3] is probably the most comprehensive analysis of the mechanism and the complications it introduced, so writing "it has always been inherently inaccurate" is just wrong, this new mechanism was way worse than just introducing unbiased sampling noise.

But why?? Differential privacy works? It's not even "woke" or whatever these people perceive. It's just math man...
Stalin's demographic researchers kept disappearing until they came up with the numbers he wanted.
The dueling political demands of accuracy and privacy are simply incompatible at some level. After reading this, maybe Hanlon's Razor isn't the right standard. Besides malice and stupidity, there is impossibility. Some problems just aren't solvable under certain constraints. I don't envy the statisticians tasked with finding a politically palatable solution to a math problem.
But the strength of differential privacy is that you can now make this tradeoff explicit and quantify it. I always liked it because it offers a mathematical solution to a policy problem, but then of course it's up to us to decide what parameters and tradeoff to choose. Also, some data might just not get published at all if the privacy implications are too problematic, so differential privacy might buy you more signal!
Yeah, the main issue with differential privacy is that you need competent government officials making decisions who understand math beyond a high school level.
It offers a mathematical description of a policy tradeoff, and the policy makers are apparently setting one of the parameters to zero.
There's a ton of information in the US that is accessible to various degrees--especially through the the deep web much less background investigations. Unless you're a wealthy person who can set up various levels of trusts you can't really hide them.
You can of course disagree about what what should actually be part of a transparent public record. (Though I suspect a lot of people post-date what was generally available in a "phone book.")
I really have to take the anti-noise side here. I get why it's a hard problem, and I get why the Census Bureau thought this was a neat solution. But I'm imagining an accountant stepping through a similar chain of logic:
* I want to accurately report the finances of our company to the best of my ability.
* But that report would allow people to reconstruct private data about the terms of our contracts with various counterparties. I'd really like to avoid that, there's no rule that says we're supposed to release that data. In fact some of those contracts probably came with nondisclosure agreements!
* So here's what I'm going to do. I'm going to calculate our results to the best of my ability, and then I'm going to add random values to them and report only the randomized ones. Any reconstruction people try to do will be wrong because of the randomness.
* If the SEC says "no, you need to report your actual numbers", I will explain to them that there's no such thing as an actual number because all data is noisy.
I can't get behind it.
if you want to keep your sanity, I suggest silently adding the phrase

Representative Joyce Beatty is from Ohio and was instrumental in stopping Trump from illegally renaming the Kennedy Center.
https://www.theatlantic.com/culture/2026/06/kennedy-center-b...
Representative Beatty serves her own interests and her involvement Kennedy Center naming was just more of the same performative politics she routinely engages in. She's on the verge of being an octogenarian and missed a number of key votes, like the bill that cut funding to NPR, PBS, and other govt. programs. Kudos to her for working to remove Trump's name from the Kennedy Center but she needs to go.
The removal of his name is not performative since we're in the thick of a cult of personality president (at a bare minimum).
Frankly i see no reason to keep this data private. They should simply publish a full dataset of the census, with no such data coarsening/differential privacy/ etc...
Fundamentally this is public data. If it's to dangerous to make public, it's too dangerous to collect, and people should be aware of exactly what it is.
There are very few things that the state has data on that should not be made public. Census data is simply not one of those things.
publishing should be the default for any data, and to keep it unpublished should require substantially good reasons that impact the country as a whole. Frankly, if it isn't detailed national defence plans, i struggle to see any data that should not be public.
How hard have you thought about this?
The biggest challenge with running a census is getting people to trust you enough to answer your questions.
A lot of census questions are sensitive. The ACS covers topics like citizenship status, disabilities, income, SNAP assistance, languages spoken at home.
If you want accurate information about the people who live in your country you need the census process to feel as safe for people to respond to as possible.
Are you saying the census shouldn't collect any data that people wouldn't be comfortable publishing? Because that's a recipe for a census that is far less useful for helping the country make useful decisions.
> Are you saying the census shouldn't collect any data that people wouldn't be comfortable publishing? Because that's a recipe for a census that is far less useful for helping the country make useful decisions.
I'll say that. The state representatives should provide congress and the president any data needed to inform policy decisions about the people they represent. And as others have pointed out, other departments and agencies (such as the IRS) have most of the rest of the data required to make policy decisions.
Except for gerrymandering purposes, I fail to see why income, party affiliations, etc., is useful for the purpose the census was created for.
The census doesn't collect party affiliations.
https://www.census.gov/topics/public-sector/voting/about/faq...
> the CPS Voting and Registration Supplement does not ask any questions of a partisan nature.
>And as others have pointed out, other departments and agencies (such as the IRS) have most of the rest of the data required to make policy decisions.
There are laws in place forbidding government agencies from merging together datasets.
The last thing people should support is creating of profiles of individuals by combining data from different government agencies. This is why the census is so important as a data collection mechanism.
> There are laws in place forbidding government agencies from merging together datasets.
This is an excellent point. In my opinion, such laws are a good idea. Most of the time, policy decisions should not require IRS data. (Or other personal data.)
But to get around such laws, the government asks citizens to provide that data a second time (in the census). And sometimes it's asked yet again on other forms. This seems to defeat the purpose of those laws.
I can see that federal disaster aid might need to know if some area needs more or less aid, depending on the wealth of the area receiving aid. If aid is given to individuals, the have a need to know the individuals' income.
When there is a reasonable need to know, I would prefer the government use the much more accurate IRS data, rather than ask for people's income multiple times. The laws preventing merging federal datasets could be rethought, given what is now known about preserving privacy mathematically. I would like to see specific exemptions made, with the provided data properly anonymized to preserve privacy while serving the legitimate purpose for which the data was requested. The use of such data should require a request to congress for it.
This seemsâs like an issue created by congress. the constitution only requires a headcount by state. Maybe they should use another mechanism to collect demographic data. Since the concern is not about representation, but allocation, tax returns seem like an obvious alternative and they are already private and collected at a much more granular level.
I don't think the question "Has this person given birth to any children in the past 12 months?" would look good on a tax return.
The census isn't for helping the country make any decisions other than determining the number of representatives and apportionment of taxes. It should not be collecting any data that isn't necessary for that.
https://constitution.congress.gov/browse/article-1/section-2...
> The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.
The key thing you're missing is "in such Manner as they shall by Law direct".
Congress has passed a whole bunch of laws that attach additional responsibilities to the census for the purpose of supporting government decisions.
The Permanent Census Office Act of 1902 for example, which established the census office and tacked on "an annual survey of cotton production, and other economic censuses" https://www.census.gov/about/history/historical-censuses-and...
That's not true, they also wanted to get an understanding of who they were governing.
I'd like to know when they stopped publishing census data. I have used it for genealogical purposes to track ancestors: you can see exactly who was living in which house, how they are related, and what their ages are (I found that women in my family often reported, both on the census and marriage documents, being younger than they actually were). I don't think I've seen data from after 1950, though.
I don't understand why the census would include SNAP data or income: surely the government already has that information. I have never doubted that the IRS knows my income better than I do. Maybe better use of existing datasets could restrict the census to less invasive questions.
They haven't stopped but they don't happen immediately.
Detailed census records are published 72 years after they were collected; the last release (of 1950 census data) came out in 2022; the next one should be published in 2032.
See: https://www.archives.gov/research/census
They didn't stop publishing census data. Its publication is delayed for approximately one human lifetime, to avoid affecting the living:
https://prologue.blogs.archives.gov/2022/01/20/census-record...
The Census Bureau is a lot more than the 10-year Census, and it already makes very extensive use of IRS data and other administrative sources. Virtually everything that is published using these sources uses either differential privacy or other privacy protection methods that are prohibited by the order. I'm guessing that a lot of those pieces of data are just going to be put on hold until the order is reversed or weakened. A number of things might have to go away permanently, as there's almost certainly no way to protect privacy in them without some kind of noise infusion.
TBH I don't think the people who wrote this knew how much collateral impact it would have.
Thank you for writing a much more thoughtful reply to this comment than I was drafting
Replying to the ACS with accurate information is required by law, so they don't actually need to rely on people feeling safe to get answers.
I don't trust the Census Bureau with my data, so if this is as "dangerous" as the author and some people here seem to think, they shouldn't be collecting it in the first place.
> Replying to the ACS with accurate information is required by law, so they don't actually need to rely on people feeling safe to get answers.
This works by the same principle as how nobody ever drives faster than the speed limit.
I don't understand your point here. Are you saying compliance isn't enforced?
As someone who got an ACS survey not long ago and had no interest in completing it, it certainly appears to be.
There's not many cases of enforcement. Non-response is taken about as seriously as the RobinsonâPatman act. I think the Census Bureau is very reliant on people thinking there will be enforcement, however, which is why the materials they send all have a threatening aura. I don't know about the ACS, but for the decennial census I often felt like my job as an enumerator was just to bother people until they'd answer. The case would keep being recycled until we got at least (IIRC) a head count.
They can certainly enforce that you answer the survey. But it's very difficult to enforce a requirement that people answer questions accurately, particularly when they perceive that doing so will expose them to danger.
I don't get what danger is being referenced here that exists only if the data is released to the public (in aggregate)?
The government is the primary and arguably only source of the danger, and they already have most of the data whether you answer the ACS correctly or not.
1. People give the information to the government under the expectation that this data is to be kept private or used in such a way that individual targeting is made impossible, you break that expectation and people will lie or won't give you this data.
2. Without noise injection it's rather simple to do statistical attacks to reverse engineer individual entities.
3. This data is and has already been used in the past to undermine democratic systems by targeting and disenfranchising minorities, as well as gerrymandering the US to hell.
4. "Too dangerous to make public, too dangerous to collect" - this is a false dichotomy. To govern effectively you need sensitive data, but it should be collected and used in a way that's safe for the individuals.
5. Macro level aggregates don't need individual exposure, that's why noise, anonymization and statistical functions are fine.
Re point 1, not just an expectation, and explicit legal requirement.
> They should simply publish a full dataset of the census, with no such data coarsening/differential privacy/ etc...
They do. After a substantial delay. Pretty handy for geneological research, while protecting privacy for the living.
That's a good default position, and I think should be our starting point.
But the devil is in the details. If we don't want advertisers constructing semi-complete profiles from simple web interactions then why would we publish 330 million census questionnaires for their use?
So do you believe that individual income should be public? Or do you believe that the government should not take income into account for taxation or distribution of benefits?
Then dox yourself right now with your previous census answers and PII. There are several obvious reasons to keep the data private, all you have to do is use your brain.
I've never met a "privacy is irrelevant" advocate that doesn't close the door when they go to the toilet
Donât quit your day job. One guess as to what gender, sexual orientation, and skin colour you have.
But why is the census asking about those attrbutes at all. The Constitution requires a count. That's it. A number. We don't need to know the rest of it, or if we do, it should be surveyed separately with voluntary participation.

But we do. A detailed census is essential for making good policy. For example, knowing the age and distribution of children across the country helps local and state governments decide where to put the next school or children's hospital. The federal govt. allocates funds for education and daycare accordingly.
The census is the best and most important measure of govt. policy. Taking it away would leave everyone worse off.
The risks of abuse are too high and historically proven to happen eventually. There are many other ways to determine where schools and hospitals are needed, such as aggregate enrollment and admission statistics.

You do realize there are places where there aren't schools or hospitals?
Local school districts know where they need more or fewer schools. This sort of thing isn't any business or responsibilty of the federal government at all.
The census is already voluntary LOL. So weâd have two censuses?
Census participation is not voluntary. Failure to provide complete or accurate data is, in theory, punishable by a fine. Last census, I intentionally provided incomplete data on the web form, which resulted in a person with a clipboard and some stern questions showing up at my door.
We can make them more accurate by leveraging ICE going door to door.
