State and County Reports

Ohio is aging as a state, but each county has its own story to tell. Explore Ohio population data and population projections at the state and county level. Delve into socio-economic characteristics like income level, marital status, education and more to discover how your community is likely to change over the coming decades.

Projections of Ohio's older adult population

Download a visualization of how Ohio’s older population is changing over the next 30 years. The table shows the number and percentage of older adults in each age group: 60+, 65+, and 85+. The chart shows how the proportion of older adults in the population changes over time.

Population Projections

The population data and projections for 2020– 2050 are from Ohio Development Services Agency.

These data contain updated population projections, by age and sex, for the state of Ohio and its 88 counties, for five-year intervals through the year 2050. This projection series was produced to align the Ohio projections with the most recent population estimates issued by the U.S. Census Bureau and with the demographic changes that occurred between 2010 and 2020, and accounts for individuals in group quarters housing (such as college dormitories and correctional facilities).

State- and county-level population characteristics

Many of Ohio's counties have relatively small population sizes. Over half of the counties in Ohio have fewer than 65,000 people (the threshold for single-year representative data). To have a large enough sample size to give accurate estimates at the county-level requires multiple years of data collection. The data labeled 2013-2018 is an average of data collected between January 1, 2013 and December 31, 2018. For simplicity, in the county reports, we refer to this as 2015 data, but it is actually collected during this five-year period. See the ACS website for more details.

Can you tell me more about the 2013-2017 versus 2015 data?
