Census 2020 of Population & Housing
  -- integrated with American Community Survey 2020
  -- data access & use resources
  -- Census 2020 is here; optimize its use in meeting your goals

April 2021. The first 2020 decennial census geography data were released January 2021. The TIGER 2020 Digital Map Database includes shapefiles developed for use with Geographic Information System (GIS) software.

Demographic Data Access
The initial Census 2020 demographic data to be released will be the re-apportionment state population totals by April 30, 2021, for use in the apportionment of the U.S. House of Representatives. More detailed data, to the census block level will be released starting in mid-August 2021. The Census 2020 data are closely integrated with the American Community Survey (ACS) and Census model-based estimates program data. Selected dates associated with release/availability of key data resources are summarized below. The ACS 2020 data will be closely associated with the Census 2020 data.

Decennial census data are important for many reasons. Among these reasons is the required role of these data in the House of Representatives reapportionment and redistricting. These data are widely used for reapportionment and redistricting for state legislatures, special districts, cities, school districts and other geographies. Businesses and other organizations rely on these data for planning, marketing and evaluation. Researchers use these data for wide-ranging analyses.

Census 2020 Subject Matter. Detailed information on the scope of the Census 2020 subject matter will be added to this section. The scope of subject matter is limited by the questions asked on the Census 2020 questionnaire.

Decennial Census Integrated with Related Data. While the decennial census is a specific data collection and tabulation program, it closely integrates with several other Census Bureau programs. These include the American Community Survey (ACS), building permits and construction program (building permits), model-based population and housing estimates program (MDE), TIGER geographic database, among several others.

Data Access, Integration, Analytics & Insights. ProximityOne Census 2020 data access and use tools enable you to use Census 2020 data alone or in combination with other data. We develop current estimates and projections using decennial census data with other data.
