Download Memorandum 2021.15 [PDF - <1.0 MB]

This memorandum describes how administrative data was used in the 2020 Census. The intended use of administrative data and the expected sources of data evolved throughout the research and planning for the 2020 Census and their actual use was expanded during 2020 Census fielding. This report documents the final use of administrative data during the 2020 Census. It updates and can replace the similar “intended” use memo made public in 2020.

The 2020 Census Memorandum Series

The 2020 Census Memorandum Series documents significant decisions, actions, and accomplishments of the 2020 Census Program for the purpose of informing stakeholders, coordinating interdivisional efforts, and documenting important historical changes.

  1. A major program level decision that will affect the overall design or have significant effect on 2020 Census operations or systems.
  2. A major policy decision or change that will affect the overall design or significantly impact 2020 Census operations or systems.
  3. A report that documents the research and testing for 2020 Census operations or systems.
