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.
