How to read these numbers
- These are estimates from a survey, not a count. The American Community Survey asks a sample of households. The ± figure is the Census Bureau’s margin of error: the true value is very likely within that range of the estimate. Small places have large margins.
- “Too imprecise to report” means the margin of error is at least half of the estimate, so printing the number would suggest accuracy that does not exist. A “rough guide only” note means the margin is a quarter to a half of the estimate.
- Property tax bill and home value are medians for owner-occupied homes. Half of the homes are above the figure and half below. A median bill is not the rate set by a city or town; the bill combines taxes levied by every local government that serves the home, such as the school district and county.
- “Calculated” rows are worked out by Untax the Roof from the Census figures above them. They compare two medians, so they describe the place, not a particular household.
- Missing is not zero. Where the Census Bureau publishes no figure, this page says so.

If property taxes go unpaid in Ohio
How it works. County tax foreclosure under ORC Chapter 5721/Chapter 323, including ordinary judicial sale and alternative-redemption-period transfer procedures; tax-certificate foreclosure is a related route
Excess sale money. ORC 5721.20 requires excess sale proceeds after writ/interest/costs to go to court clerk after confirmation; owner is notified. Unclaimed residue moves to county treasury after notice but remains demandable by owner for 3 years, then forfeits to designated county fund. Section excludes most transfers without sale under 323.78 except specified cross-reference
