Dayton-Cincinnati CSA Merger
According to an article in the Cincinnati Enquirer, as Greater Cincinnati grows northward through Butler County, it is expected to eventually merge with Greater Dayton by 2013, thereby virtually erasing any distinguishable boundary between the two current Combined Statistical Areas (CSA). As a result, the US Census Bureau will begin reporting the Cincinnati and Dayton metropolitan areas as one by that time. The new Cincinnati-Dayton metroplex will be comparable in nature to that of Baltimore-Washington's and place it within the top 20 most populous metros in the US with a population of nearly 3.1 million.
