2020 Census Redistricting Data (P.L. 94-171) Shapefiles

Released in groups of states January 2021 through February 2021. Once complete, the 2020 Census Redistricting Data (P.L. 94-171) Shapefiles will be available for all 50 states, the District of Columbia, and the Commonwealth of Puerto Rico.

Why should you care if your not interested in the politicians and their self-serving redistricting efforts? Well, TIGER/Line data is very useful for making all kinds of maps where you need county and municipal lines, such as mapping cases of COVID-19 or any data you get from data.census.gov. Or even hiking or road maps when you want town lines on them.

The nice thing about the redistricting files is they are packaged up in nice big ol’ ZIP file for the whole state coverage, for easy downloading and use. Mid-redistricting cycle you will want to occasionally get the yearly updates to reflect changes in county, municipal and census tract lines, but those have to be individually downloaded. It’s better to download one big file, and have all the data you need at one shot.
