Map Gallery

This site presents an archive of maps derived from the 2022 U.S. Census of Governments, which I have created to visualize the distribution of local government units across the United States. Currently, these maps are organized by county and by core-based statistical areas. Additional aggregations may be added in the future.

Map types

• All local governments
• All general-purpose local governments (municipalities and towns/townships)
• Municipalities
• Towns/townships
• School districts (combined independent and dependent)
• Special districts
• Special districts per municipality
• Hirschmann-Herfindahl Index (\(1- \sum_{n=1}^5 share_{type}^2\))
