California School District Areas 2025-26

This layer serves as the authoritative geographic data source for all school district area boundaries in California. School districts are single purpose governmental units that operate schools and provide public educational services to residents within geographically defined areas. Agencies considered school districts that do not use geographically defined service areas to determine enrollment are excluded from this data set. In order to view districts represented as point locations, please see the "California School District Offices" layer. The school districts in this layer are enriched with additional district-level attribute 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. School districts are categorized as either elementary (primary), high (secondary) or unified based on the general grade range of the schools operated by the district. Elementary school districts provide education to the lower grade/age levels and the high school districts provide education to the upper grade/age levels while unified school districts provide education to all grade/age levels in their service areas. Boundaries for the elementary, high and unified school district layers are combined into a single file. The resulting composite layer includes areas of overlapping boundaries since elementary and high school districts each serve a different grade range of students within the same territory. The 'DistrictType' field can be used to filter and display districts separately by type. Boundary lines are maintained by the California Department of Education (CDE) and are effective in the 2025-26 academic year . The CDE works collaboratively with the US Census Bureau to update and maintain boundary information as part of the federal School District Review Program (SDRP). The Census Bureau uses these school district boundaries to develop annual estimates of children in poverty to help the U.S. Department of Education determine the annual allocation of Title I funding to states and school districts. The National Center for Education Statistics (NCES) also uses the school district boundaries to develop a broad collection of district-level demographic estimates from the Census Bureau’s American Community Survey (ACS). The school district enrollment and demographic information are based on student enrollment counts collected on Fall Census Day (first Wednesday in October) in the 2025-26 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.

本图层为加利福尼亚州所有学区区域边界的权威地理数据源。学区为单一职能政府单位，负责运营学校并向地理划定范围内的居民提供公共教育服务。未通过地理划定服务区域确定招生范围的学区机构，不纳入本数据集。若需查看以点位形式呈现的学区，请参阅「加利福尼亚州学区办事处」图层。
本图层的学区数据整合了加利福尼亚州教育部（California Department of Education, CDE）采集的额外学区级属性信息。此类数据元素可提供具备实用价值的统计与描述性信息，支持在地图上进行可视化与分析，用于推进教育研究或辅助决策制定。
学区根据其运营学校的总体年级范围，分为小学（初等）学区、高中（中等）学区与综合学区三类：小学学区为低学段/低龄群体提供教育服务，高中学区服务高学段/高龄群体，综合学区则在其服务区域内为全学段/全年龄段群体提供教育服务。
小学、高中及综合学区图层的边界被整合为单个文件。由于小学与高中学区可在同一辖区内服务不同学段的学生，因此合并后的复合图层存在边界重叠区域。可通过「学区类型（DistrictType）」字段按类型筛选并单独显示各类学区。
学区边界由加利福尼亚州教育部（CDE）维护，生效于2025-2026学年。作为联邦学区审查计划（School District Review Program, SDRP）的一部分，加利福尼亚州教育部与美国人口普查局（US Census Bureau）合作更新并维护学区边界信息。人口普查局利用此类学区边界数据编制年度贫困儿童估算数据，协助美国教育部确定向各州及学区拨付Title I资助金的年度额度。美国国家教育统计中心（National Center for Education Statistics, NCES）同样利用学区边界数据，基于人口普查局的美国社区调查（American Community Survey, ACS）编制全面的学区级人口统计估算数据集。
本数据集的学区招生与人口统计信息，基于2025-2026学年秋季普查日（10月第一个周三）收集的学生招生人数。此类数据元素由加利福尼亚州教育部通过加利福尼亚纵向成就系统（California Longitudinal Achievement System, CALPADS）收集，可从加利福尼亚州教育部官网的「数据与统计」页面（https://www.cde.ca.gov/ds）以公开可下载文件的形式获取。
