Operation Purpose

The Post-Enumeration Survey (PES) includes three operations with the following responsibilities:

  • Coverage Measurement Design and Estimation operation (CMDE): Designs the PES, including sampling and estimation.
  • Coverage Measurement Matching operation (CMM): Identifies matches and nonmatches between the 2020 Census and the PES for the enumerated housing units (HUs) and people.
  • Coverage Measurement Field Operations (CMFO): Collects person and HU information (independent from the 2020 Census operations) for the sample of HUs in the PES.

The PES is an interrelated set of operational activities intended to allow the Census Bureau to evaluate coverage of the 2020 Census and provide data to improve future censuses. The Census Bureau conducts the PES to measure the coverage of housing units and people residing in housing units in the 2020 Census.
