Statewide Database

The Statewide Database (SWDB) is the redistricting database for the state of California. In 2001, 2011, and 2021 these data were used for state legislative and local redistrictings following the 2000, 2010, and 2020 Censuses as mandated by law. Data collection and processing for the redistricting are ongoing tasks conducted over a ten year period of time, starting with the collection of the census at the beginning of each decade. With each election between redistrictings, updated data sets are available as a free, public resource as soon they are processed.
