California's State Assembly districts are numbered 1st through 80th, generally in north-to-south order.
The California State Assembly is the lower house of the California State Legislature . The Assembly has 80 members, each representing one district.
In accordance with the Article XXI of the California Constitution , assembly district boundaries are redrawn every ten years based on data from the United States Census . The current boundaries were drawn in 2020 by a California Citizens Redistricting Commission and finalized in 2021. The census enumerated population of each district was within 1% of 465,674 with an average absolute deviation of 0.506%.[ 1]
Due to the state's large population and relatively small legislature, the Assembly has the largest population per representative ratio of any lower house legislature in the United States ; only the federal U.S. House of Representatives has a larger ratio. Since Proposition 28 passed in 2012, members of the Legislature are limited to a total of 12 years of legislative service, which can be served in the Assembly, Senate, or a combination of both.
The Democratic State Central Committee, the governing body of the California Democratic Party , elects roughly 1/3 of its members from Assembly district election meetings held biennially in January in every odd-numbered year within each of the 80 Assembly districts.[ 2] [ 3]
