Census Bureau suggests 'significant' number of noncitizens missed in 2020 tally

A simulation run by the Census Bureau estimates that nearly one-fifth of noncitizens living in the U.S. were not tallied in the 2020 census.

Almost a fifth of noncitizens found in the administrative records had addresses that couldn’t be matched in the 2020 census, suggesting that "a significant fraction of noncitizens" were missed, according to the U.S. Census Bureau report released Friday. By comparison, that same figure was 5.4% for citizens.

Using administrative records from government agencies that have records on immigration, welfare programs, motor vehicle registrations and other data, the test tallied 2.3% more people than in the actual census in 2020 that produced a head count of 331 million U.S. residents, primarily because the simulation captured more noncitizens residing in the U.S., the report said.
