What this state directory covers

The list uses Census Population Estimates Program place records (summary level 162): mostly incorporated cities, towns and villages, with their official labels and identifiers. Unincorporated communities and most census-designated places are outside this release, so a named community can be absent even though people live there, and the place totals above are smaller than the state population. Annual changes can reflect boundary adjustments as well as population change. Dollar figures are ACS 2020–2024 five-year medians in 2024 dollars, joined by exact place GEOID.
