2020 Census Redistricting Data (P.L. 94-171) TIGER/Line Shapefiles
Downloaded 1/26/2021 from https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html
Documentation file: https://www.census.gov/programs-surveys/geography/technical-documentation/complete-technical-documentation/tiger-geo-line.html
The 2020 Census Redistricting Data (P.L. 94-171) TIGER/Line Shapefiles contain 2020 and 2010 geographic extent and boundaries of both legal and statistical entities (which have no governmental standing) for the United States, the District of Columbia, and the Commonwealth of Puerto Rico. The 2020 vintage includes boundaries of governmental units that match the data from the surveys that use 2020 geography (e.g., 2020 Population Estimates and the 2020 American Community Survey). The 2010 vintage includes boundaries of governmental units that match the data from the surveys that use 2010 geography (e.g., 2010 Population Estimates and the 2010 American Community Survey).
In addition to geographic boundaries, the 2020 Census Redistricting Data (P.L. 94-171) TIGER/Line Shapefiles also include geographic feature shapefiles and relationship files. Feature shapefiles represent the point, line and polygon features in the MTDB (e.g., roads and rivers). Relationship files contain additional attribute information users can join to the shapefiles. Both the feature shapefiles and relationship files reflect updates made in the database through October 2020.
