Metro Dayton or the Miami Valley, or more formally the Dayton–Kettering–Beavercreek, OH Metropolitan Statistical Area, as defined by the United States Census Bureau, is an area consisting of three counties in the Miami Valley region of Ohio and is anchored by the city of Dayton.
As of the 2020 census this has still not occurred due to criteria not being met for combined area designation Greater Dayton is part of the Great Lakes Megalopolis containing an estimated 54 million people.
Smaller growths in the 2010 census in the Dayton area included Miamisburg, Centerville, Vandalia, and Fairborn.
As a result of new Census criteria to delineate metropolitan areas, Preble County was eliminated from the MSA in 2013 as it no longer qualified for inclusion.
In addition to the Benjamin and Marian Schuster Performing Arts Center,[12] the Dayton Region's largest performing arts center, Greater Dayton has a vibrant theater community throughout the region.
