For Immediate Release: Thursday, March 17, 2022

2020 Census Post-Enumeration Survey Results Available for 50 States and DC in May

Press Release Number CB22-CN.04

Coverage Rates by Census Operation for the Nation Also Available

MARCH 17, 2022 — The U.S. Census Bureau today announced undercount and overcount rates by state and the District of Columbia from the 2020 Census Post-Enumeration Survey (PES) will be released in May 2022, which is earlier than previously announced.

This spring release includes:

  • Coverage estimates for states: Undercount and overcount rates and components of coverage by state and the District of Columbia (a state equivalent).
  • National components of coverage: Correct or erroneous enumerations and whole-person imputations by census operation – including internet response mode, and nonresponse follow-up by type of enumeration: by a householder, a proxy respondent, and administrative record enumeration. 

Results will not be broken down by demographic characteristics or geographic areas within the state. Following the 2010 PES, the Census Bureau did not release state estimates of coverage by demographic groups. Given the sample size for the 2020 PES and the assumptions required to make substate estimates, we cannot include county or place estimates in the 2020 PES reports.

The remainder of the PES estimates, including results for housing units, and undercount and overcount rates for Puerto Rico, are scheduled for release in the summer.

The Census Bureau released the first results from the PES along with additional results from the 2020 Demographic Analysis (DA) on March 10. The first release of PES results provided estimates of population coverage overall and by demographic groups, such as race and Hispanic origin, as well as age groups and sex. DA results included net coverage error estimates by age and sex.

The PES creates an estimate of the number of people living in the United States on April 1, 2020 (excluding people in group quarters, such as nursing homes or college dorms, and people in Remote Alaska), by surveying a sample of people in the United States and matching their records to the 2020 Census.
