2020 Census data releases

Click on a tab below to access various 2020 Census data products. Some of the data files are large and may require additional time to download.

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.
