Redistricting Data Release

08.12.2021

On August 12, 2021, the U.S. Census Bureau released redistricting "legacy" data to the states. Although these data will require some time to process, this is the information states and localities need to draw new voting districts that are designed to last for the entire decade. The updated schedule for releasing these data has impacted state redistricting and election timelines. Learn more here.

The 2021 redistricting cycle will create maps that states will use in their elections for the next 10 years. That is why it is crucial that states’ redistricting processes provide ample opportunity for public testimony. This allows members of the public to provide valuable information to the mapmakers about their community – where it is located, who lives there, and why it is important that the community is kept whole – and to provide feedback on draft or final maps.  

After every decennial census, the Census Bureau provides states with the data needed for redistricting. This year, as a result of an adjusted census timeline, states will receive processed population data needed for redistricting by September 30, 2021. This is several months later than in previous census cycles. 

The new schedule will affect legally mandated redistricting deadlines and risk a reduction in the time the public has to provide meaningful input about their communities to decision-makers.
