The 2030 census plan now faces an April 1 deadline in Congress

The public has had its say on the Trump administration's plan for the 2030 census. Now the clock is running. The comment period closed November 2 with 143,238 comments filed, and federal law requires the Commerce Department to tell Congress what subjects the census will cover by April 1, 2027, less than five months away.

The proposed rule would leave many noncitizens out of the count used to divide House seats, count people where they spent the most days between January 3 and April 1, and bar questions on race, ethnicity, and sexual orientation from the census form. It remains a proposal, and it gives no date for a final version.

The next step belongs to the U.S. Census Bureau and the Commerce Department, which have to work through the comments. The Supreme Court put the rule this way in 2015: "An agency must consider and respond to significant comments received during the period for public comment." The agency can still go ahead over objections, since a comment period doesn't work like a vote. But any final rule has to explain its reasoning, and it generally can't take effect until 30 days after it is published.

The comments lean heavily against the plan. An analysis by Hands Off Our Census, a coalition of groups that oppose the rule, found that 112,178 of the 126,120 comments published as of November 3, or 89 percent, were against it. Opponents include six former Census Bureau directors, 14 business groups, and state and local officials.

The two reports to Congress come from Title 13 of the U.S. Code. The law says the commerce secretary must report the subjects no later than three years before the census and the questions no later than two years before. The secretary can change them later only by finding that "new circumstances exist."

The last census shows why those reports matter. Commerce delivered its 2020 questions on March 29, 2018, including one on citizenship. States and advocacy groups sued, and in 2019 the Supreme Court blocked the question, saying the government's stated reason "seems to have been contrived."

A similar fight looks likely. Attorneys general from 23 states and the District of Columbia have already called the plan unlawful. Courts generally review an agency's final action, so a lawsuit would most likely come after a final rule.

Congress could also step in, and its makeup is about to change. NBC News projects that Democrats will control both the House and the Senate beginning in January. Lawmakers can change census law, though any bill would need the president's signature or enough votes to override a veto. A bill from Rep. Andrew Clyde of Georgia would push in the opposite direction, adding a citizenship question and excluding noncitizens from the count for House seats.

Money is the nearer deadline. The Census Bureau is running at its fiscal 2026 funding level under a stopgap bill that expires December 11, with some flexibility to spend more on 2030 preparations. Commerce's inspector general warned in October that the bureau needs money to test new methods. "Without adequate testing, the bureau will not be able to verify that its census operations will work as intended," the report said.
