A county map should make the boundaries easy to read and the source easy to verify. These maps are drawn from the U.S. Census Bureau’s 2025 cartographic boundary files and generated as lightweight SVG. That keeps lines sharp on high-density screens and paper without loading a heavy interactive map application.
The atlas includes more than entities literally named “county.” Louisiana uses parishes, Alaska has boroughs and census areas, Connecticut now uses planning regions, and several states include independent cities. The Census Bureau treats these as county-equivalents, so they belong in a complete national view.
