Directory figures are live counts from the Churches List database for Ohio (OH) as of June 2026. Congregations and adherents come from the 2020 US Religion Census, a county-level enumeration reported by religious bodies and aggregated here to the state; its methodology differs from a directory count and the two will not match. Historic-register counts join National Register of Historic Places listings to directory churches. Statistics for other states: Texas · California · Pennsylvania · North Carolina · Florida · Illinois · Georgia · New York · Michigan · Tennessee.
