WASHINGTON (AP) — The 2020 U.S. Census will include a question about citizenship status, a move that brought swift condemnation from Democrats, who said it would intimidate immigrants and discouraging them from responding.

The population count taken every 10 years is more than an academic exercise. It's required by the Constitution and used to determine the number of seats each state has in the House as well as how federal funds are distributed to local communities. It helps communities determine where to build everything from schools and grocery stores to hospitals.

A coalition of state attorneys general urged the department last month to not add such a question, saying it could lower participation among immigrants and cause a population undercount.

California Attorney General Xavier Becerra said the state will sue the Trump administration over its decision.
