Earlier this week, The Census Bureau announced that the 2020 census will include a question about citizenship. The decision led a number of states to sue the Trump administration. The New York Times summarized the controversy this way:
"The Constitution requires that every resident of the United States be counted in a decennial census, whether or not they are citizens. The results are used not just to redraw political boundaries from school boards to House seats, but to allocate hundreds of billions of dollars in federal grants and subsidies to where they are needed most. Census data provide the baseline for planning decisions made by corporations and governments alike.
Opponents of the added citizenship question said it was certain to depress response to the census from noncitizens and even legal immigrants. Critics accused the administration of adding the question to reduce the population count in the predominantly Democratic areas where more immigrants reside, in advance of state and national redistricting in 2021."
