Dayton is a community rich in talent and history, emerging today as a global technology hub. The City of Dayton is investing for the future while providing high-quality services to residents, neighborhoods and businesses. The sixth largest city in the state, Dayton is the county seat for Montgomery County, which is the fifth most populous county in the state. Dayton plays host to significant industrial, aerospace, and technological/engineering research activity and is known for the many technical innovations and inventions developed there. Much of this innovation is due in part to Wright-Patterson Air Force Base and its place within the community. With the decline of heavy manufacturing, the Dayton economy has diversified into a service economy, including the insurance and legal sectors and most importantly the healthcare and government sectors. Dayton was rated the #3 city out of the top 50 cities in the United States by HealthGrades for excellence in health care. Many hospitals in the Dayton area are consistently ranked by Forbes, U.S. News and World Report, and HealthGrades for clinical excellence.
