Click a column heading to sort all 15 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.

- Calculated: medians across counties = middle value of the county values (mean of the two middle values for an even count) (method)
- Calculated: spreads = highest county value ÷ lowest county value (method)
- Calculated: income tiers vs poverty = mean poverty rate of the N highest- and N lowest-income counties, N = min(10, ⌊counties ÷ 2⌋), only for states with ≥ 6 counties (method)
- Calculated: rankings and superlatives = highest / lowest county value; suppressed values excluded (method)
