The Trump administration just proposed a rule that would exclude illegal immigrants from the population count used to divvy up the 435 seats in the U.S. House of Representatives. The rule, set to be published in the Federal Register on Thursday, would also exclude legal immigrants who don't hold permanent resident status — meaning green card holders count, but visa overstays and border jumpers do not.
California, Florida, and Texas stand to lose seats. Alabama, Minnesota, and Ohio stand to gain them.
The proposed rule, built around the 2030 census, argues that "illegal aliens (among others) should not be included in the apportionment count, as they are not true inhabitants, members of the body politic, or persons with a 'usual residence' in the state." That's the Census Bureau's own language, citing the 14th Amendment's requirement to count "the whole number of persons in each State" — and making the case that people residing here illegally don't qualify as inhabitants with sufficient ties and allegiance to the country.
President Trump put it more directly on Truth Social: "People who are in our Country illegally WILL NOT BE COUNTED IN THE CENSUS."
According to a 2025 Pew Research study, roughly 16 million immigrants currently live in the United States without permanent legal status. That's 16 million people who, under the current system, inflate the congressional representation of whichever state they happen to be standing in when the census taker knocks. Pew's own modeling from 2020 estimated the distortion was worth approximately 3 House seats — seats awarded not to citizens, but to the jurisdictions that attracted the most illegal immigration.
Senator Bill Hagerty, Republican of Tennessee, has already introduced S. 2205 in the 119th Congress to codify the exclusion of undocumented immigrants from the 2030 apportionment count. The House passed a companion bill, H.R. 7109, back in 2024. The legislative framework exists. The executive branch is now moving in the same direction.
New York Attorney General Letitia James responded exactly the way you'd expect. "We stopped the Trump administration's census attacks in 2020, and we're exploring our legal options to fight back again," she said. Which is a remarkable way to describe the act of ensuring that American citizens — and only American citizens — determine American political representation. The word she used was "attacks." On a census form.
This isn't new ground for Trump. He tried to exclude illegal aliens from apportionment during his first term, but the COVID-19 pandemic delayed the 2020 count long enough for Joe Biden to take office and shelve the effort. The legal fight made it all the way to the Supreme Court, which never ruled on the merits because the question became moot after the administration changed. This time, the proposal arrives with four years of runway before the 2030 count and a sympathetic Congress that's already moving legislation.
The proposal also strips race, ethnicity, and sexual orientation questions from the census — a move that will generate its own headlines. But the apportionment change is the one with structural consequences. Congressional districts are drawn based on census population totals. Federal funding formulas use the same data. Every illegal alien counted in a sanctuary city is a fraction of a House seat and a slice of federal dollars that wouldn't exist if the count reflected actual citizens.
Three House seats may not sound like much. But elections have been decided by single seats. Speakerships have hinged on margins smaller than three. And those three seats currently sit in states that built their political power partly on populations that can't legally vote, can't legally work, and in many cases entered the country by breaking the law.
The census is supposed to count Americans so Americans can govern themselves. Funny how controversial that becomes when you actually try to do it.
