Memorandum 2018.13: 2020 Census Plans for the Commonwealth of Puerto Rico

Memorandum 2018.13

This memorandum documents the 2020 Census Program decision regarding address list updates and enumeration in the Commonwealth of Puerto Rico during the 2020 Census.


As a result of the devastating impact of Hurricane Maria, the Census Bureau has determined that it is in the best interest of Puerto Rico to conduct the Update Leave (UL) operation across the entire commonwealth during the 2020 Census. The UL operation will update the address list and feature data for the area assigned, and leave a questionnaire package at every housing unit identified, to allow the household to self-respond.

Under this operation, all respondents in Puerto Rico will have the ability to respond to the 2020 Census by internet (including Non-ID), telephone, or a paper questionnaire hand-delivered to every housing unit. Households that do not respond will be included in the Nonresponse Followup operation, where field enumerators will make an in-person contact attempt to determine the status of the housing unit and, when occupied, collect the census response.

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.

A memorandum generally will be added to this series for any decision or documentation that meets the following criteria:

  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.
