Locales 2025

This data layer produced by the National Center for Education Statistics’ (NCES) Education Demographic and Geographic Estimates (EDGE) program provides a geographic locale framework that classifies all U.S. territory into twelve categories ranging from Large Cities to Remote Rural areas. NCES uses this framework to describe the type of geographic area where schools and school districts are located. The criteria for these classifications are defined by NCES and rely on standard geographic areas developed and maintained by the U.S. Census Bureau. The NCES Locale boundaries are based on geographic areas represented in Census TIGER/Line. For more information about the NCES locale framework, and to download the data, see: https://nces.ed.gov/programs/edge/Geographic/LocaleBoundaries. The classifications include: City – Large (11): Territory inside an urban area with population of 50,000 or more and inside a principal city with population of 250,000 or more. City – Midsize (12): Territory inside an urban area with population of 50,000 or more and inside a principal city with population less than 250,000 and greater than or equal to 100,000. City – Small (13): Territory inside an urban area with population of 50,000 or more and inside a principal city with population less than 100,000. Suburban – Large (21): Territory outside a principal city and inside an urban area with population of 250,000 or more. Suburban – Midsize (22): Territory outside a principal city and inside an urban area with population less than 250,000 and greater than or equal to 100,000. Suburban – Small (23): Territory outside a principal city and inside an urban area with population less than 100,000 and greater than or equal to 50,000. Town – Fringe (31): Territory inside an urban area with population less than 50,000 that is less than or equal to 10 miles from an urban area with population of 50,000 or more. Town – Distant (32): Territory inside an urban area with population less than 50,000 that is more than 10 miles and less than or equal to 35 miles from an urban area with population of 50,000 or more. Town – Remote (33): Territory inside an urban area with population less than 50,000 that is more than 35 miles from an urban area with population of 50,000 or more. Rural – Fringe (41): Territory outside an urban area that is less than or equal to 5 miles from an urban area with population of 50,000 or more, as well as territory outside an urban area that is less than or equal to 2.5 miles from an urban area with population less than 50,000. Rural – Distant (42): Territory outside an urban area that is more than 5 miles but less than or equal to 25 miles from an urban area with population of 50,000 or more, as well as territory outside an urban area that is more than 2.5 miles but less than or equal to 10 miles from an urban area with population less than 50,000. Rural – Remote (43): Territory outside an urban area that is more than 25 miles from an urban area with population of 50,000 or more and is also more than 10 miles from an urban area with population less than 50,000.
