SEPTEMBER 21, 2023 — The U.S. Census Bureau today released 2020 Census population counts and sex-by-age statistics for 300 detailed race and ethnic groups, as well as 1,187 detailed American Indian and Alaska Native (AIAN) tribes and villages.
These data come from the 2020 Census Detailed Demographic and Housing Characteristics File A (Detailed DHC-A). Previously, the Census Bureau released 2020 Census data on the Hispanic or Latino population and major race groups such as White, Black or African American, Asian, etc.
Today’s release adds information on detailed groups within those major categories such as German, Lebanese, Jamaican, Chinese, Native Hawaiian and Mexican — and on AIAN tribes and villages like the Navajo Nation. The release includes information about more than 200 detailed race and ethnic groups not tabulated from previous censuses.
“These 2020 Census data illuminate the rich diversity across our nation,” said Rachel Marks, chief of the Census Bureau’s Racial Statistics Branch. “We have this comprehensive picture thanks to the millions of people who responded to the census and provided their detailed racial, ethnic or tribal identity, and thanks to the stakeholders, researchers and tribal leaders who helped us improve how we collect these detailed data.”
Among the highlights, the Detailed DHC-A reveals the largest detailed groups within the major race groups and the Hispanic population. For the race groups, data are available for both the race alone population and the race alone or in any combination population. The race alone population represents the minimum number of people who identified as that group. It includes those who reported only one response, such as only Fijian. The race alone or in any combination population represents the maximum number of people who identified as that group. It includes those who reported only one response, such as Fijian, and those who reported multiple responses, such as Fijian and Japanese or Fijian and Black or African American.
Comparisons between the 2020 Census and 2010 Census detailed race data should be made with caution and take into account improvements made to the race question and to the way the Census Bureau codes responses. However, the detailed Hispanic origin data from the ethnicity question are comparable between the two censuses. More information about the changes made to the way detailed race and ethnicity groups were coded for the 2020 Census is available in the blog What You Should Know About the Upcoming Detailed Demographic and Housing Characteristics File A.
More information about the detailed groups is available in the America Counts stories:
The Census Bureau also published a working paper on Understanding Counts of Afro-Latino Responses in the 2020 Census, presenting the different ways of tabulating Afro-Latino responses.
The Census Bureau will release stories about the detailed populations within the Hispanic, American Indian and Alaska Native, White, Black or African American, and Some Other Race populations over the next few weeks.
The Detailed DHC-A data are available in the interactive visualization Detailed Races and Ethnicities in the United States and Puerto Rico: 2020 Census. This visualization maps the largest and second largest detailed groups by state and county and provides ranking lists of detailed groups by racial or ethnic group and by geography.
The complete set of Detailed DHC-A tables are also available on data.census.gov. For assistance accessing and using the data, check out the short videos and how-to guides with screenshots in the Detailed DHC-A press kit.
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 and is described in more detail in the blog Data Quality for Detailed Race and Ethnicity Groups and American Indian and Alaska Native Tribes and Villages in the 2020 Census.
