FEB. 12, 2021 — The U.S. Census Bureau announced today that it will deliver the Public Law 94-171 redistricting data to all states by Sept. 30, 2021. COVID-19-related delays and prioritizing the delivery of the apportionment results delayed the Census Bureau’s original plan to deliver the redistricting data to the states by March 31, 2021.
Different from previous censuses, the Census Bureau will deliver the data for all states at once, instead of on a flow basis. This change has been made because of COVID-19-related shifts in data collection and in the data processing schedule and it enables the Census Bureau to deliver complete and accurate redistricting data in a more timely fashion overall for the states.
The redistricting data includes counts of population by race, ethnicity (Hispanic or Latino origin), voting age, housing occupancy status, and group quarters population, all at the census block level. This is the information that states need to redraw or “redistrict” their legislative boundaries.
In preparation for the delivery of redistricting data products, the Census Bureau has been in close coordination with each states’ official nonpartisan liaisons to understand the impacts of the delayed delivery on individual states. Since 2019, states have had access to prototype geographic support products and data tabulations from the 2018 Census Test to help them begin to design their redistricting systems. This is one tool states can use to help minimize the impact of schedule delays. In addition, the Census Bureau today completed the release of all states’ 2020 Census geographic products needed for redistricting. This will enable states to redistrict promptly upon receipt of their 2020 Census tabulation data.
