Detailed Demographic and Housing Characteristics File A
This release contains 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.
Counts are available at the national and state level. For substate geographies, including counties, places, census tracts, and American Indian/Alaska Native/Native Hawaiian areas, the counts must meet minimum population thresholds to be shown. Depending on the population size of the racial or ethnic group in a given geography, age and sex data may be available for 4, 9, or 23 age categories. Please see the Detailed Demographic and Housing Characteristic File A release page and 2020 Census Detailed Demographic and Housing Characteristics File A (Detailed DHC-A) Technical Documentation for more details.
The full Detailed Demographic and Housing Characteristics File A can be accessed from data.census.gov. State and County level data are also available in the Detailed Race and Ethnicity in the United States and Puerto Rico: 2020 Census visualization. You may find the following How to Find Population counts for Detailed Race and Hispanic Origins helpful to learn how to use this visualization.
Below we have aggregate race and ethnicity data from the DHC release and the detailed race and ethnicity data from the Detailed DHC-A release for the total population. Keep in mind there are many more tables available from the DHC release and age and sex detail available from the Detailed DHC-A release that are not shown here.

Redistricting data will be released in legacy format on August 12. OFM plans to post data in easy to use excel or csv formats within a few days of its release.
The redistricting data includes counts of population by race, ethnicity (Hispanic or Latino origin), voting age, housing occupancy status, and group quarters population down to the census block level. This data will be used to redraw legislative boundaries and boundaries of other jurisdictions that elect representatives using internal districts (counties, cities, schools, ports, and fire districts). Census data will also be used to distribute more than $1.5 trillion in federal funds to states, counties and cities, and to influence public and private decision-making related to education, healthcare, transportation and many more issues.

The tables included herein have been created by the Washington State Redistricting Commission, ESRI and CityGate GIS. They are based on the U.S. Census Bureau’s 2020 Redistricting Data Summary File, also known as the Public Law 94-171 file. In accordance with RCW 44.05.140, the population, race and ethnicity data were adjusted at the Census block level in a manner that reflects the last known place of residence of inmates incarcerated in state adult correctional facilities, persons committed to receive involuntary behavioral health treatment, and persons residing or placed in juvenile justice facilities.
