2020 Census Detailed Demographic and Housing Characteristics File A Press Kit
The 2020 Census Detailed Demographic and Housing Characteristics File A (Detailed DHC-A) includes detailed data tables on the following:
Subjects: Population counts and sex-by-age statistics for approximately 1,500 detailed racial and ethnic groups, such as German, Lebanese, Jamaican, Chinese, Native Hawaiian, and Mexican, as well as American Indian and Alaska Native (AIAN) tribes and villages like the Navajo Nation.
Geographies: Nation, state, county, places (cities and towns), census tracts, and American Indian/Alaska Native/Native Hawaiian (AIANNH) areas.
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. This approach allows the Census Bureau to produce as much detail as possible while ensuring strong confidentiality protections.
