This executive summary focuses on the key results, conclusions, and recommendations from the 2020 Nonresponse Followup (NRFU) Operational Assessment (OA) Report.

The purpose of the 2020 NRFU operation was twofold: 1) to determine the housing unit status for addresses that did not complete a census questionnaire, and 2) to enumerate the housing units that were occupied on April 1, 2020. Because of its scale, NRFU has historically been the largest and most expensive field operation of the decennial census.
