Click a column heading to sort all 9 planning regions. A suppressed estimate (coefficient of variation ≥ 0.30) shows a marker, never a guess. County seats are from Wikidata (CC0), each validated to a Census place inside its county. Where Wikidata has none, the seat comes from the page cited for that county in the seat file, and where the table names no seat, it says why. See the methodology.

A row marked (balance) is the Census Bureau’s “balance” of a consolidated city: its population leaves out the separately incorporated places inside the consolidated city (methodology).
