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.
