Memorandum 2019.27: 2020 Early Nonresponse Followup Universe
Memorandum 2019.27: 2020 Early Nonresponse Followup Universe
Memorandum 2019.27
This memorandum documents the creation of the Early Nonresponse Followup (NRFU) universe for the 2020 Census.
The purpose of Early NRFU is to enumerate college and university students who live in off-campus housing before the end of the spring semester when they may leave for another residence. The 2020 Early NRFU operation will begin on April 9, 2020.
To create the Early NRFU universe, Census Bureau staff identified eligible schools and the geographic area surrounding each school based on certain criteria, including the school’s semester end date and the number of full-time students. Stakeholders from the regional census centers and the Federal-State Cooperative for Population Estimates reviewed and refined the Early NRFU universe based on their local knowledge and research. This work was completed in August 2019 with the Census Bureau’s quality control review of updates from stakeholders. The Early NRFU universe began the process to become part of the enumeration universe for the 2020 Census in September 2019.
The number of housing units in each state that will be eligible for Early NRFU are below.
