The controversial new citizenship question the Trump administration added to the 2020 census may turn out to be a “major barrier” to the country’s full participation in the upcoming national head count, according to a national study commissioned by the Census Bureau.

The Constitution requires every person living in the U.S. — both citizens and noncitizens — to be counted once a decade. Those population numbers are used to determine how many congressional seats and Electoral College votes each state gets.
