Updates on the 2020 Census Redistricting Data Program

Updates on the 2020 Census Redistricting Data Program and Local Government Redistricting in Tennessee

Originally presented October 27, 2020.

The release of the first sub-state 2020 Census data product next March, 2021 kicks off an important series of events across Tennessee. After a decade of population shifts, cities and counties will review population changes to determine if political districts, ranging from County Commission to City Council, comply with applicable laws regarding population variation and if necessary redraft them.

The 2020 Census Redistricting Data files used for this process will be the subject of our second fall webinar series event.
