More than 4 million people — including a significant portion of black and Latino Americans — could be left out of the 2020 census, according to a study from the nonpartisan Urban Institute.
"Unprecedented threats" facing the 2020 census, such as under-funding, hiring issues, inadequate testing and the potential addition of a citizenship question, could lead to the under-count, which would disproportionately affect minorities.
Conducted every 10 years, the census is required by the Constitution. The results have an outsize influence on the nation's economy and political power. It determines the number of seats in the House of Representatives each state gets and affects the dispersal of billions of federal dollars that go toward schools, hospitals, roads and a number of other vital areas.
