2025 Cartographic Boundary File (SHP), Division for United States, 1:5,000,000

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 08:32 PM | Dataset Last Updated: May 01, 2026 at 12:00 AM
The 2025 cartographic boundary shapefiles 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. Divisions are groupings of states within a census geographic region, established by the Census Bureau for the presentation of census data. The current nine divisions (East North Central, East South Central, Middle Atlantic, Mountain, New England, Pacific, South Atlantic, West North Central, and West South Central) are intended to represent relatively homogeneous areas that are subdivisions of the four census geographic regions.
