The U.S. Census Bureau has spent much of the past year defending itself against allegations that its duties have been overtaken by politics. With a failed attempt by the Trump administration to add a citizenship question, the hiring of three political appointees with limited experience to top positions, a sped-up schedule and a directive from President Donald Trump to exclude undocumented residents from the process of redrawing congressional districts, the 2020 census has descended into a high-stakes partisan battle.

The U.S. Census Bureau is releasing new population data that will be used to reshape U.S. House seats and state legislative districts for the next decade. The data being released Thursday shows the population of counties, cities and neighborhoods in the 2020 census. That will serve as the building block for redistricting that must be done in most states before the 2022 elections. The official goal is to redraw districts with roughly the same number of people. But many Republicans and Democrats also will be trying to draw districts that make it more likely for their candidates to win.
