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.
