2020 Census Geography

The United States Census Bureau publishes geographic units used for tabulation of the 2020 Census population data in the 2020 TIGER/Line Shapefile. The geographic units, which remain constant throughout the decade, include counties, census tracts, block groups, and blocks. Fields have been added so data formatted or published by the council can be joined to the shapefile for analysis.

Each Shapefile (.shp) is in a compressed file (.zip) format.

  • Blocks.zip - Census Blocks
  • BlockGroups.zip - Block Groups
  • Tracts.zip - Census Tracts
  • Counties.zip - Counties
  • Cities.zip - Census Places (Cities)
  • CDPs.zip - Census Designated Places

Each 'Pop' file contains the 2020 Census population for the corresponding geographic level.

  • BlocksPop.zip - Census Blocks 2020 Census Population
  • BlockGroupPop.zip - Census Block Groups 2020 Census Population
  • TractsPop.zip - Census Tracts 2020 Census Population
  • CountiesPop.zip - Counties 2020 Census Population
