Clermont County has been one of the most rapidly growing counties in Ohio , both in terms of total numbers and growth percentages, over the past thirty years. From 1970 to 1980, the population grew from just under 100,000 to about 128,000, an increase of 32%. From 1980 to 1990, there was a 17% increase, bringing the population to roughly 150,000, the population in 2000 was 177,977, a 19% increase, and the population in 2010 was 197,363, a 10.9% increase. Estimates for 2014 show the population already at 201,560, a 2.1% increase since 2010.
Much of the County’s growth has been concentrated in two western townships adjacent to Hamilton County along I-275. The southeast and northeast portions of the County remain somewhat rural. Over 1,150 miles of highways connect residents. Regional public transit service has improved since the implementation of the Clermont Transportation Connection, but is still limited. Arranging transportation for persons with mental health and substance abuse issues is frequently difficult.
The rapidly growing population has placed stress on many social and governmental institutions serving the community. Social indicators illustrate these stressors. Rates for DUI, divorce, and addiction and drug overdoses are higher than the state averages.
