About 2020 Census Data Products

The apportionment results and redistricting data are now available, and there’s much more to come from the 2020 Census.

We are developing the next set of 2020 Census data products and are moving deliberately to ensure that we can produce the high-quality statistics that the public expects. The pandemic delayed our operations, and we’re in the midst of implementing new confidentiality protections.

Below are descriptions of these products, including their planned lowest level of geography covered 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:

  • As we develop the data products, we are taking time to balance accuracy in the detailed information with our confidentiality obligations.
  • We will determine the final content for these products based on data user feedback and disclosure avoidance 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.

2020 Census Apportionment Results

Apportionment is the process of dividing the 435 memberships, or seats, in the U.S. House of Representatives among the 50 states. At the conclusion of each decennial census, the results are used to calculate the number of seats to which each state is entitled.

  • Subjects: Resident population, overseas population, and apportionment population
  • Geographic Detail: 50 States, the District of Columbia, and Puerto Rico
  • Access: 2020 Census Apportionment Results
  • Date: Released April 26, 2021

Redistricting Data Summary File (P.L. 94-171)

Public Law 94-171 directs the Census Bureau to provide the data that may be used for redistricting to the governors and the officers or public bodies having responsibility for redistricting in each of the 50 states.

This product is the first from the 2020 Census that includes demographic and housing characteristics about detailed geographic areas including states, counties and places.

  • Subjects: Voting age, race, Hispanic or Latino origin, housing occupancy status, group quarters population by major group quarters type
  • Lowest level of geography: Census block
  • Access: FTP site in August (links to data files and support materials are available on the Decennial Census P.L. 94-171 Redistricting Data Summary Files page); data.census.gov on September 16
  • Date: Released on FTP August 12, 2021; the same data released on data.census.gov on September 16, 2021

Demographic Profile

This product will provide selected demographic and housing characteristics about local communities.

  • Subjects: 5-year age groups, sex, race, Hispanic or Latino origin, household type, relationship to householder, group quarters population, housing occupancy, and housing tenure.

  • Access: data.census.gov. 

  • Lowest level of geography: Places and minor civil divisions (MCDs). 

  • Planned release date: May 2023.

Demographic and Housing Characteristics File (DHC)

The DHC will include many of the demographic and housing tables previously included in the 2010 Census Summary File 1 (2010 SF1). Some tables are repeated by race and ethnicity.

  • 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.

  • Lowest level of geography: Varies, with many tables proposed at the census block level. 

  • Planned release date: May 2023. The graphic below provides more information on the timeline for development and production.

Congressional District Summary Files

This product retabulates selected summary levels from the Demographic and Housing Characteristics File (DHC) for the 118th Congress and new state legislative districts. If states report additional changes for future congressional sessions (e.g., 119th, 120th, etc.), the Census Bureau will regenerate the summary file using the new boundaries. If no changes for a future session are reported, the previously generated congressional district 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.

  • Proposed 2020 geographies: Congressional districts, state legislative districts and other selected geographies.

  • Planned release date: August 2023.

Detailed Demographic and Housing Characteristics File (Detailed DHC)

Based on data user feedback and development of the disclosure avoidance system, we’ve split the Detailed DHC into three separate products described below. 

  • The Detailed DHC-A and Detailed DHC-B will provide statistics for detailed racial and ethnic groups and American Indian and Alaska Native tribes and villages.   

  • The Supplemental-DHC will provide characteristics about people within households.

More information about specific tables planned for these products is available in the August 2022 version of the 2020 Census Data Product Planning Crosswalk.

Detailed Demographic and Housing Characteristics File A (Detailed DHC-A)

  • Subjects: Population counts and sex by age statistics for approximately 370 detailed racial and ethnic groups, such as German, Lebanese, Jamaican, Chinese, Native Hawaiian, and Mexican, as well as about 1,200 detailed American Indian and Alaska Native tribal and village population groups, such as Navajo Nation.

  • Access: data.census.gov.

  • Proposed 2020 geographies: Nation, state, county, and American Indian/Alaska Native/Native Hawaiian (AIANNH) areas. We’re evaluating the feasibility of adding places (cities and towns) and census tracts, per data user feedback.

  • Planned release date: August 2023. The graphic below provides more information on the timeline for development and production.

Detailed Demographic and Housing Characteristics File B (Detailed DHC-B)

  • Subjects: Household type and tenure information for the same detailed race and ethnicity groups and American Indian and Alaska Native tribal and village population groups mentioned for the Detailed DHC-A. 

  • Access: data.census.gov.

  • Proposed 2020 geographies: Nation, state, county, and American Indian/Alaska Native/Native Hawaiian (AIANNH) areas.

  • Release date: To be determined. 

Supplemental Demographic and Housing Characteristics File (S-DHC)

The S-DHC tables reflect especially complex relationships between the characteristics about households and the people living in them. These complex characteristics supplement the data about households and people available in the DHC product. We often refer to these tables as “complex person-household join tables” or “join tables.”  Some tables are repeated by race and ethnicity.

  • Subjects: Data that combine characteristics about households and the people living in them, including the total population in households, average household size by age and tenure, average family size, household and family type for people under 18 years old, and total population in households by tenure. 

  • Access: data.census.gov.

  • Proposed 2020 geographies: Varies with many tables available at the nation, state, county, census tract, places, and AIANNH areas. 

  • Release date: To be determined.
