California State Senate district boundaries intended for the NEVI map.Data downloaded in October 2024 from https://gis.data.ca.gov/maps/b31d93f08c074753b89f8cbb0b8beed9/about.

Polygon layers for the 2011 and 2022 Senate district boundaries and the 2022 Assembly district boundaries.

This is the last boundary change until the next redistricting following the 2030 Census. All of the districts now reflect the 2021 Citizens Redistricting Commission(CRC) plan. The only thing that will change is the members' names and parties as elections are held, appointments are made, or party affiliations change.Senate Districts feature layer is updated as-needed and we expect to update it more regularly in the future.Schema:F2020_POP: The 2020 population of the district as reported by the census.F2020_HU: Number of housing units in the district in 2020 as reported by the census.CRC_POP: Citizen's Redistricting Commission population.District: The District is the district number.Party: The Party is the party represented.last_name: The last name is the last name of the representative.first_name: The first name is the first name of the representative.district_website: The district website is the link to the district website.For more information about the F2020_Pop and the F2020_HU visit: https://www.census.gov/programs-surveys/decennial-census/about/rdo/summary-files.html

Final approved map by the 2020 California Citizens Redistricting Commission for the California State Senate.

Final 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.

This resource is a member of a series. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. State Legislative Districts (SLDs) are the areas from which members are elected to State legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the state legislature. Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation; there are no data by SLDL for either Nebraska or the District of Columbia. A unique three-character census code, identified by state participants, is assigned to each SLD within a state. In Connecticut, Illinois, Louisiana, New Hampshire, Wisconsin, and Puerto Rico, the Redistricting Data Program (RDP) participant did not define the SLDs to cover all of the state or state equivalent area. In these areas with no SLDs defined, the code "ZZZ" has been assigned, which is treated as a single SLD for purposes of data presentation. The most recent state legislative district boundaries collected by the Census Bureau are for the 2022 election year and were provided by state-level participants through the RDP.

The legislative districts contain the geographically defined territories used for representation in the California State Assembly, California State Senate and the U.S. House of Representatives from California. These three boundary layers were approved by the California Citizens Redistricting Commission in 2021 following the completion of the 2020 United States Census.

This dataset is one from a series of district layers pertaining to California Senate Districts that are derived from the California State Senate information. All data layers are reprojected into the SCAG standard projection. The following district layer is included in the series: Senate_districts: Current California Senate Districts based on the new district boundaries enacted into state law on September 13, 2001, and signed into law on September 13, 2001, and signed into law on September 26, 2001 for use with the March 2002 primary election The boundary has been updated as of 11/2011

California State Senate boundaries adopted for the June 2012 primary elections. Districts located within the County of San Diego were extracted and reprojected into SanGIS standard projection.Every 10 years, after the federal census, California must redraw the boundaries of its Congressional, State Senate, State Assembly, and State Board of Equalization districts, to reflect the new population data. Now those lines are drawn by the Commission. California voters authorized the creation of the Commission when they passed the Voters First Act, which appeared as Proposition 11 on the November 2008 general election ballot. Under the Act, the Commission is charged with drawing the boundaries of California’s Congressional, Senate, Assembly and Board of Equalization electoral districts.The commission has14 members from varied ethnic backgrounds and geographic locations in the state and includes five Democrats, five Republicans, and four Decline to State.http://wedrawthelines.ca.gov/
