2020

All 2020 Census data products have been released. 

Additional data products may be requested through the Decennial Census Special Tabulation program for the cost of producing them.

Below are the descriptions of the 2020 Census data products, including their lowest level of geography and release dates. These data products are for public use and may be accompanied by graphs, maps, reports, and results in other forms.

A few notes:

  • In developing the data products, we have taken the time to balance data confidentiality, data accuracy, and data availability.
  • We determined the final content for these products based on data user feedback and new disclosure avoidance system development and testing. More information is available on the Developing the DAS: Demonstration Data and Progress Metrics webpage.
  • We will continue to update this webpage as information becomes available.

Congressional District Summary Files

This product retabulates 2020 Census Demographic and Housing Characteristics File (DHC) tables for selected summary levels related to newly districted Congressional and state legislative districts. For each congressional session, if any state reports changes to their congressional district boundaries, the Census Bureau regenerates the tables using those new boundaries. If no changes for any state for a congressional session are reported, the previously generated congressional district summary file is used as both its original and subsequent congressional session product, and no re-tabulation is created.

  • Subjects: Age, sex, race, Hispanic or Latino origin, household type, family type, relationship to householder, group quarters population, housing occupancy and housing tenure.

  • Access: data.census.gov and FTP

  • Geographies: Congressional districts, state legislative districts and other selected geographies.

  • Geographies: Nation, state, county, places (cities and towns), census tracts, and American Indian/Alaska Native/Native Hawaiian (AIANNH) areas. Please note, the amount of data available for the detailed racial and ethnic groups and AIAN tribes and villages depends on their population size within a specific geography.
