Challenges threatening the upcoming 2020 census could risk more than 4 million people to be missing from next year’s national head count, according to new projections by the Urban Institute.

The nonpartisan think tank found that the danger of an inaccurate census could hit some of the country’s most difficult-to-count populations the hardest. Based on the Urban Institute’s analysis, the 2020 census could lead to the worst undercount of black and Latinx people in the U.S. since 1990.
