Aerial imagery of the contiguous United States with every state boundary drawn on top. Alaska and Hawaii are not in this frame: a single Web Mercator rectangle holding both Alaska and Florida spans half the planet and would leave the lower 48 too small to read. Their own state pages carry their own imagery.

The boundary is the 2025 Census cartographic boundary file, reprojected to Web Mercator to match the imagery. You can also open the USGS National Map viewer.

Every state

Most and fewest

Texas has more counties than any other state by a margin of 95. Why that happened, and why the national total is not a settled number.

Three things a national county map does not show

  • Not every entity is a county. Louisiana has parishes, Alaska has boroughs and census areas, Connecticut has planning regions, and 40 independent cities belong to no county at all. Nine legal types in total.
  • 35 of them have no county government. Connecticut and Rhode Island abolished theirs, Massachusetts abolished most of its, and Alaska's census areas never had one. The full list.
  • The boundaries move. Connecticut's changed in 2022, three Alaska entities changed shape in 2013 while keeping their identifiers, and counties are occasionally renamed, which usually forces a new FIPS code. Why codes change.
