Dortmund (German: [ˈdɔʁtmʊnt] (listen); Westphalian Low German: Düörpm [ˈdyːœɐ̯pm̩]; Latin: Tremonia) is the third-largest city in North Rhine-Westphalia and the eighth-largest city of Germany, with a population of 603,609 inhabitants as of 2020. It is the largest city (by area and population) of the Ruhr, Germany's largest urban area with some 5.1 million inhabitants, as well as the largest city of Westphalia. On the Emscher and Ruhr rivers (tributaries of the Rhine), it lies in the Rhine-Ruhr Metropolitan Region and is considered the administrative, commercial, and cultural center of the eastern Ruhr. Dortmund is the second-largest city in the Low German dialect area after Hamburg.
Founded around 882, Dortmund became an Imperial Free City. Throughout the 13th to 14th centuries, it was the "chief city" of the Rhine, Westphalia, and the Netherlands Circle of the Hanseatic League. During the Thirty Years' War, the city was destroyed and decreased in significance until the onset of industrialization. The city then became one of Germany's most important coal, steel and beer centres. Dortmund consequently was one of the most heavily bombed cities in Germany during World War II. The devastating bombing raids of 12 March 1945 destroyed 98% of buildings in the inner city center. These bombing raids, with more than 1,110 aircraft, hold the record to a single target in World War II.The region has adapted since the collapse of its century-long steel and coal industries and shifted to high-technology biomedical technology, micro systems technology, and also services.

Dayton () is the sixth-largest city in the state of Ohio and the county seat of Montgomery County. A small part of the city extends into Greene County. The 2019 U.S. census estimate put the city population at 140,407, while Greater Dayton was estimated to be at 803,416 residents. This makes Dayton the fourth-largest metropolitan area in Ohio and 63rd in the United States. Dayton is within Ohio's Miami Valley region, just north of Greater Cincinnati.
Ohio's borders are within 500 miles (800 km) of roughly 60 percent of the country's population and manufacturing infrastructure, making the Dayton area a logistical centroid for manufacturers, suppliers, and shippers. Dayton also hosts significant research and development in fields like industrial, aeronautical, and astronautical engineering that have led to many technological innovations. Much of this innovation is due in part to Wright-Patterson Air Force Base and its place in the community. With the decline of heavy manufacturing, Dayton's businesses have diversified into a service economy that includes insurance and legal sectors as well as healthcare and government sectors.
Along with defense and aerospace, healthcare accounts for much of the Dayton area's economy. Hospitals in the Greater Dayton area have an estimated combined employment of nearly 32,000 and a yearly economic impact of $6.
