2020 Decennial Census Demographic Profiles and DHC Data ReleasedPosted on May 25, 2023 in Decennial Census, Featured, Main, Whats New Releases
Today, the U.S. Census Bureau released the 2020 Census Demographic Profile and Demographic and Housing Characteristics File (DHC).
This release includes data and cross tabulations by age group, race group, Hispanic or Latino origin, and sex. There are additional data on families, households, and group quarters. These releases do not include detailed race data. Those data will be released in the Detailed DHC-A data, expected in September 2023.
The Demographic Profile provides an overview of 2020 Census data down to the tract level, and the DHC provides detailed data down to the tract or block level. Blocks are the smallest unit of geography released by the Census Bureau. However, the Census Bureau encourages data users to aggregate small populations to improve accuracy.
Below are links to some key data and publications from this release:
