Unified School District Boundaries 2025

From the 2019 TIGER/Line Technical Documentation: The Census Bureau obtains school district boundaries, names, local education agency codes, grade ranges, and school district levels annually from state education officials. The Census Bureau collects this information for the primary purpose of providing the U.S. Department of Education with annual estimates of the number of children aged 5 through 17 in families in poverty within each school district, county, and state. This information serves as the basis for the Department of Education to determine the annual allocation of Title I funding to states and school districts. The 2023 118th Congressional District TIGER/Line Shapefiles include separate shapefiles for elementary, secondary, and unified school districts. The 2020 shapefiles contain information from the 2020 school year (i.e., districts in operation as of January 1, 2020). Unified school districts provide education to children of all school ages. In general, if there is a unified school district, no elementary or secondary school district exists. If there is an elementary school district, the secondary school district may or may not exist. In addition to regular functioning school districts, the TIGER/Line Shapefiles contain pseudoschool districts.摘自2019年TIGER/Line技术文档：美国人口普查局（Census Bureau）每年从各州教育主管部门获取学区边界、名称、地方教育机构代码、学段范围以及学区层级信息。该局收集此类信息的核心目的，是为美国教育部提供各学区、县及州范围内，处于贫困家庭的5至17岁儿童数量的年度估算值。该数据是教育部确定向各州及学区拨付《初等和中等教育法》第一部分（Title I）年度资助资金的依据。 2023年第118届国会选区TIGER/Line形状文件（Shapefiles）包含针对小学学区、中学学区以及联合学区的独立形状文件。2020年版形状文件包含2020学年的相关信息（即截至2020年1月1日仍在运营的学区）。联合学区可为所有学龄儿童提供教育服务。通常而言，若某区域存在联合学区，则不会同时设有小学学区或中学学区；若存在小学学区，则可能设有也可能不设中学学区。除正常运营的学区外，TIGER/Line形状文件还包含虚拟学区（pseudoschool districts）。
