Ohio’s 88 counties, by the numbers

The table lists every county’s population, median household income, unemployment, density, and land area. Sort it by any column to find yours or rank them. A few patterns stand out:

  • Income tracks poverty. The gap from richest to poorest runs 2.5×, and the 10 highest-income counties average 7.0% in poverty against 18.1% for the 10 lowest. calculated from Census SAIPE 2024
  • The median county. Half of Ohio’s counties have fewer than 58,320 residents, and half report a median household income below $68,793. calculated from Census PEP V2025 · Census SAIPE 2024
  • Lopsided density. Only 21 of 88 counties are denser than Ohio’s statewide average of 291 people per square mile. calculated from Census PEP V2025 · Census TIGER 2026

Click a column heading to sort all 88 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.
