As you can see, all counties but Hocking grew in both the 2020-2024 and 2023-2024 periods. Most of the estimates were improvements over the 2023 version, as mentioned. For example, Franklin County’s estimates population in 2023 was 1,326,063, but the 2024 version for 2023 was revised to 1,338,903, indicating growth was significantly stronger than originally estimated.

2019 Ohio County Population Estimates

2019 Ohio county population estimates

The US Census has begun releasing 2019 population data, which will be the final data before we get the official, decennial census statistics for 2020. With Covid-19 ravaging the world and United States at the moment, it remains to be seen what effects it might have on the census counts, or if the official census may even end up delayed. While we wait for those issues to resolve, here are the 2019 Ohio county population estimates.
