California Citizens Redistricting Commission
California State Assembly Districts Map 2020Final approved map by the 2020 California Citizens Redistricting Commission for the California State Assembly; the authoritative and official delineations of the California State Assembly drawn during the 2020 redistricting cycle. The Citizens Redistricting Commission for the State of California has created statewide district maps for the State Assembly, State Senate, State Board of Equalization, and United States Congress in accordance, with the provisions of Article XXI of the California Constitution. The Commission has approved the final maps and certified them to the Secretary of State.
Line drawing criteria included population equality as required by the U.S. Constitution, the Federal Voting Rights Act, geographic contiguity, geographic integrity, geographic compactness, and nesting. Geography was defined by U.S. Census Block geometry.
80 Assembly districts have an ideal population of around 500,000 people each, and in consideration of population equality, the Commission chose to limit the population deviation range to as close to zero percent as practicable. With these districts, the Commission was able to respect many local communities of interest and group similar communities; however, it was more difficult to keep densely populated counties, cities, neighborhoods, and larger communities of interest whole due to the district size and correspondingly smaller number allowable in the population deviation percentage.

California Citizens Redistricting Commission
California State Senate Districts Map 2020Final approved map by the 2020 California Citizens Redistricting Commission for the California State Senate; the authoritative and official delineations of the
California State Senate drawn during the 2020 redistricting cycle. The
Citizens Redistricting Commission for the State of California has
created statewide district maps for the State Assembly, State Senate,
State Board of Equalization, and United States Congress in accordance,
with the provisions of Article XXI of the California Constitution. The
Commission has approved the final maps and certified them to the
Secretary of State.
Line drawing criteria included population equality as required by the U.S. Constitution, the Federal Voting Rights Act, geographic contiguity, geographic integrity, geographic compactness, and nesting. Geography was defined by U.S. Census Block geometry.
Each of the 40 Senate districts has an ideal population of nearly one million people and represents the largest state legislative districts in the nation. In consideration of population equality, the Commission chose to limit the population deviation as close to zero percent as practicable. Per the California Constitution, the Commission strived to nest two Assembly districts where practicable. However, higher ranking criteria made this difficult in practice. While the size of the Senate districts allowed the Commission to recognize broadly shared interests, these interests did not always overlap exactly with the interests of smaller communities recognized in the related Assembly districts. Based on the large number of people in each district, there were a variety of different interests that were balanced and included.

California US Congressional Districts Map 2020Final approved map by the
2020 California Citizens Redistricting Commission for California's
United States Congressional Districts; the authoritative and official delineations of California's
United States Congressional Districts drawn during the 2020 redistricting cycle. The
Citizens Redistricting Commission for the State of California has
created statewide district maps for the State Assembly, State Senate,
State Board of Equalization, and United States Congress in accordance,
with the provisions of Article XXI of the California Constitution. The
Commission has approved the final maps and certified them to the

Line drawing criteria included population equality as required by the U.S. Constitution, the Federal Voting Rights Act, geographic contiguity, geographic integrity, geographic compactness, and nesting. Geography was defined by U.S. Census Block geometry.
Each of the 52 Congressional districts apportioned to California have an ideal population of 760,066, and the Commission adhered to federal constitutional mandates by requiring a district population deviation of no more than +/- one person. These districts also posed some of the Commission’s biggest challenges, and, because of strict population equality requirements, resulted in many more splits of counties, cities, neighborhoods, and communities of interest compared to State Assembly or Senate plans.
