Click a column heading to sort all 66 counties. 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.
