School Districts in Arizona

This composite file contains elementary, secondary, and unified school district boundaries from the 2021-2022 academic year collected for the National Center for Education Statistics by the U.S. Census Bureau and reported in TIGER/Line 2022. ADHS downloads the composite file, and restructures it to support spatial joins to point data, especially for elementary and secondary schools districts, which frequently overlap. Source Data The National Center for Education Statistics’ (NCES) Education Demographic and Geographic Estimate (EDGE) program develops annually updated school district boundary composite files that include public elementary, secondary, and unified school district boundaries clipped to the U.S. shoreline. School districts are special-purpose governments and administrative units designed by state and local officials to organize and provide public education for local residents. District boundaries are collected for NCES by the U.S. Census Bureau to support educational research and program administration, and the boundaries are essential for constructing district-level estimates of the number of children in poverty. The Census Bureau’s School District Boundary Review program (SDRP) (https://www.census.gov/programs-surveys/sdrp.html) obtains the boundaries, names, and grade ranges from state officials, and integrates these updates into Census TIGER. Census TIGER boundaries include legal maritime buffers for coastal areas by default, but the NCES composite file removes these buffers to facilitate broader use and cleaner cartographic representation. The inputs for this data layer were developed from Census TIGER/Line 2020 and represent boundaries reported for the 2019-2020 school year.

Last Updated: June 2023 Update Frequency: As Needed本复合文件包含2021-2022学年的小学、中学及统一学区边界数据，此类数据由美国人口普查局为美国国家教育统计中心（National Center for Education Statistics, NCES）收集，并以TIGER/Line 2022格式发布。ADHS下载该复合文件并对其进行重构，以支持与点数据的空间连接，尤其适用于经常存在重叠的小学及中学学区。 源数据： 美国国家教育统计中心（NCES）的教育人口与地理估算项目（Education Demographic and Geographic Estimate, EDGE）每年更新学区边界复合文件，其中包含裁剪至美国海岸线的公立小学、中学及统一学区边界。 学区是由州及地方官员设立的特殊用途政府与行政单元，用于组织并为当地居民提供公共教育服务。 美国人口普查局为NCES收集学区边界数据，以支持教育研究与项目管理，此类边界数据对于构建学区层面贫困儿童数量估算值至关重要。 美国人口普查局的学区边界审查项目（School District Boundary Review Program, SDRP）（链接：https://www.census.gov/programs-surveys/sdrp.html）从州政府官员处获取边界、名称及年级范围，并将这些更新内容整合至人口普查局TIGER体系中。 人口普查局TIGER边界默认包含沿海地区的法定海事缓冲区，但NCES的复合文件移除了此类缓冲区，以提升数据的通用性并实现更简洁的制图表达。 本数据图层的输入数据源自2020年人口普查TIGER/Line数据集，对应2019-2020学年上报的边界信息。 如需了解NCES学区边界数据的更多信息，请访问：https://nces.ed.gov/programs/edge/Geographic/DistrictBoundaries。 最后更新时间：2023年6月 更新频率：按需更新
