Yesterday the Census Bureau released Noncitizen Voting in the 2020 Election, A Beginning Analysis, which links a commercial voter file to federal administrative records and reports ~24,000 noncitizen voters in the 2020 election, with 32 million records "yet to analyze."
The brief frames this work in terms of a Census Bureau crime-statistics mandate dating back to 1902. The history is more complicated: the 1902 act authorized decennial statistics on "crime, pauperism, and benevolence, including prisoners, paupers, juvenile delinquents, and inmates of benevolent and reformatory institutions"-in other words, counting people already in institutions, not identifying potential lawbreakers. The Bureau discontinued its national Judicial Criminal Statistics program after 1945, and its prisoner-statistics work subsequently shifted to the Justice Department.

I'm concerned about the potential chilling effect of this work. The brief notes that the analysts "did not have access to the names of the population analyzed or any other identifying information." And the Bureau is publishing aggregate statistics, not identifiable records. But this still sends a potentially troubling message about how administrative data shared with the Census Bureau might be used.
The Bureau's own research found that households containing noncitizens were particularly sensitive to citizenship-related data collection. A 2024 Census study found reduced response, increased household-roster omissions and internet breakoffs, and an increased undercount among households with noncitizens.
It's telling that no statistician or researcher put their name on this report-unlike virtually every other Census Bureau publication. Mike Schneider has a nice piece on that if you want to learn more:https://countofcounting.substack.com/p/no-researchers-name-is-on-census
Anyone have any other thoughts about this? I'd especially welcome perspectives from folks who know more about Census Bureau history than me.
