This web map displays the California Department of Education's (CDE) core set of geographic data layers. This content represents the authoritative source for all statewide public school site locations and school district service areas boundaries for the 2018-19 academic year. The map also includes school and district layers enriched with student demographic and performance information from the California Department of Education's data collections. These data elements add meaningful statistical and descriptive information that can be visualized and analyzed on a map and used to advance education research or inform decision making.

The school district enrollment and demographic information are based on student enrollment counts collected on Fall Census Day (first Wednesday in October) in the 2023-24 academic year. These data elements are collected by the CDE through the California Longitudinal Achievement System (CALPADS) and can be accessed as publicly downloadable files from the Data & Statistics web page on the CDE website https://www.cde.ca.gov/ds.

This web map of California legislative districts includes the geographically defined territories used for representation in the California State Assembly, California State Senate and the US House of Representatives from California. These three boundary layers are derived from the US Census Bureau's 2018 TIGER/Line database and are designed to overlay with the California Department of Education’s (CDE) education related GIS content.The 80 California State Assembly Districts represent the geographically defined territories used for electing members to the lower (house) chamber of the California State Legislature. The current state assembly boundaries were determined by the California Citizens Redistricting Commission following the completion of the 2010 United States Census and will remain valid until 2020.The 40 state senate districts represent the geographically defined territories used for electing members to the upper (senate) chamber of the California State Legislature. The current state senate boundaries were determined by the California Citizens Redistricting Commission following the completion of the 2010 United States Census and will remain valid until 2020.The 53 congressional districts within the State of California represent the geographically defined territories used for electing members to the U.S. House of Representatives. The current U.S. Congressional boundaries in California were determined by the California Citizens Redistricting Commission following the completion of the 2010 United States Census and will remain valid until 2020

This layer serves as the authoritative geographic data source for all school district office locations in California. District office location and attribute information are derived from the California Department of Education"s (CDE) public schools and districts directory and district enrollment file.

Since the school districts in this layer are represented as point locations instead of service areas, this layer includes additional district types that do not use geographically defined service areas to determine enrollment such as county offices of education, state special schools and State Board of Education (SBE) charter schools. In order to view districts represented as service area polygons, please see the "California School District Areas" layer.

The school district enrollment and demographic information are based on the 2023-24 academic year student enrollment counts collected on Fall Census Day in 2023 (first Wednesday in October). These data elements are collected by the CDE through the California Longitudinal Achievement System (CALPADS) and can be accessed as a downloadable file from the Census Day Enrollment File page on the CDE website.

District records are assigned X, Y coordinates using a quality controlled geocoding and validation process to optimize positional accuracy. Most district offices are mapped to the office structure or centroid of the district office property parcel and are individually verified using aerial imagery or assessor"s parcels databases. Districts are assigned various geographic area values based on their mapped locations including state and federal legislative district identifiers and National Center for Education Statistics (NCES) locale codes.

This spreadsheet identifies the legislative districts assigned to California's K-12 public school sites and school district areas. Legislative districts assignments for schools are based on the geographic intersection of the legislative territories and school facility locations. Legislative district assignments for school districts are determined by overlaying, or combining, the geographic territories of both areas and looking at where they intersect.
