2025 Cartographic Boundary File (KML), Elementary School District for Maine, 1:500,000

Published by U.S. Department of Commerce, U.S. Census Bureau, Geography Division | U.S. Census Bureau, Department of Commerce | Catalog Last Checked: May 04, 2026 at 08:38 PM | Dataset Last Updated: May 01, 2026 at 12:00 AM
The 2025 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The Census Bureau obtains the boundaries, names, local education agency codes, grade ranges, and school district levels for school districts from state education officials via the School District Review Program (SDRP). The SDRP is a U.S. Department of Education National Center for Education Statistics (NCES) sponsored program conducted annually by the U.S. Census Bureau. It is of vital importance for the state's allocation of federal funding under Title I of the Elementary and Secondary Education Act (ESEA) as amended by Every Student Succeeds Act of 2015, Public Law 114-95. The updated school district boundary information submitted through this program are used by the Small Area Income and Poverty Estimates (SAIPE) program in forming the Census Bureau's estimates of the number of children aged 5 through 17 in families in poverty for each school district. These estimates are the basis of the Title I allocation for school districts in each state. School district boundaries are also used to develop estimates of social, economic, demographic, and housing conditions from the American Community Survey (ACS), and they provide essential geographic information to help education program administrators and researchers investigate location-based questions. The cartographic boundary files include separate shapefiles for elementary, secondary, unified, and administrative school districts. The school district boundaries are those in operation as of January 1, 2025.
