Miami County: 34% · Ohio: 33%
Owners who are 65 or older, or disabled, can claim Ohio’s homestead exemption, which takes part of a home’s value off the bill; most must have an income under the state’s limit. From the U.S. Census Bureau’s American Community Survey, 2020–2024 five-year estimates (table B25007, owner-occupied homes by the age of the householder). A survey, so every figure has a margin of error.
The Census counts a township as a whole, so its figure can take in a village inside it, whose homes have a page of their own.
