The 2020 census may have missed a large share of noncitizens
A recent US Census Bureau study of government administrative data “designed to improve coverage of historically undercounted population groups” found the potential for a significant undercount of noncitizens in the 2020 Census.
NPR’s Hansi Lo Wang explains:
That gap, researchers found, was likely driven by noncitizen residents who are missing from the agency’s count, especially those with “unknown legal status.” About 19.7% of noncitizens tallied in the simulation using administrative records had addresses that could not be matched with those counted in the 2020 census.
That raises ‘the possibility that the 2020 Census did not succeed in collecting data for a significant fraction of noncitizens residing in the United States,’ the bureau’s report says.”
Undercounts lead to underrepresentation and subsequently misrepresentation in standard population data. If you work with “hard to count” populations—children under five, noncitizens, people of color, rural residents—it is imperative you go beyond population data when designing programs, policies, and funding strategies.
