Post-Enumeration Surveys

The purpose of the Post-Enumeration Survey is to measure the accuracy of the census. The survey measures the accuracy of the census by independently surveying a sample of the population.

The U.S. Census Bureau has used post-enumeration surveys with dual system estimation to measure coverage in the Decennial Censuses of Population and Housing since 1980. This approach involves case-by-case matching of people in an independent survey with people in the census to determine who was missed or counted in error.
