This memorandum documents specific updates that have been made to the plan for the Update Leave operation since the release of the Update Leave (UL) Detailed Operational Plan (DOP) on June 25, 2018. Over the last year, planning changes in other areas of the decennial census have resulted in modifications and updates to the UL workload universe. In particular, a change was made to the Military Type of Enumeration Area (TEA), as documented in the Memo Series and released on July 5, 2019. The Military Type of Enumeration Area (TEA 5) was removed from the 2020 Census. Subsequently a decision was made to integrate certain military installations into the UL Universe.

There were minimal operational impacts due to the introduction of Military TEAs/Installations into the UL workload. A detailed summary of the impacts and the locations of documentation within the UL DOP that is now outdated and what the updates would be is presented below. There will not be an additional publication of the UL DOP prior to the 2020 Census.
