1880 Ohio Census Index

This resource contains approximately 800,000 records from 87 counties in the state of Ohio. It was prepared by the Ohio Genealogical Society and represents all the Ohio counties that existed in 1880.

This publication of the Index to the 1880 Federal Population Census for the State of Ohio by the Ohio Genealogical Society is the result of thousands of volunteer hours — not only by members and friends in Ohio but out-of-state members as well.

The population of the United States more than tripled between 1850 and 1900 making the indexing of censuses for the last half of the 19th century a monumental undertaking.
