Cincinnati: Suburban Counties Gain, Core Losses

The historical core municipality of the Cincinnati metropolitan area, the city of  Cincinnati, continued its population loss string stretching back to the 1970 census and dropped below 300,000 population for the first time since the 1890 census.  The city peaked at 504,000 in 1950.

In 2010, the census counted 297,000 residents, down 10 percent from the 2000 figure of 331,000. The city of Cincinnati has essentially the same borders (city limits) as in 1950. Hamilton County, which is the core county and includes the city of Cincinnati lost 43,000 people, with a net loss of 9,000 in the portions outside the city.  

All growth was in the suburbs, which grew at a rate of 9 percent. The fastest growing counties were Boone in Kentucky at 38 percent and Warren in Ohio at 34 percent. Combined, these two counties captured more than two-thirds of the metropolitan area growth.

The Cincinnati metropolitan area, which stretches from Ohio into Kentucky and Indiana grew 6 percent, from 2,010,000 to 2,130,000.
