The Miami Valley, broadly, refers to the land area surrounding the Great Miami River in southwest Ohio, USA, and also includes the Little Miami, Mad, and Stillwater rivers as well. Geographically, it includes Dayton, Springfield, Middletown, Hamilton, and other communities.
Most commonly, however, it refers to the economic and cultural-social region centered primarily on Dayton and the Greater Dayton area, including TV and radio markets. Middletown and Hamilton both fall under the economic and cultural-social influence of Cincinnati and thus, do not commonly use the term in this sense. Institutions and enterprises in the Dayton area, such as Miami Valley Career Technology Center, Miami Valley Hospital, Miami Valley Council of the Boy Scouts of America and Miami Valley Storytellers, as well as Upper Valley Medical Center (Troy), illustrate local usage.

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.
