Demographics
As Greater Cincinnati grows northward through Butler County, it could conceivably merge with Greater Dayton by 2030, thereby virtually erasing any boundary between the two current Combined Statistical Areas (CSA). As a result, the US Census Bureau could begin reporting the Cincinnati and Dayton metropolitan areas as one by that time, though it would be up to the U.S. Office of Management and Budget to make the merger decision. The new Cincinnati–Dayton metropolitan area would be comparable in size to that of the Orlando–Deltona–Daytona Beach, FL CSA and place it within the top 20 most populous metros in the US, with a population of nearly 3.0 million.[4]
