Hancock County is a prosperous northwest Ohio county centered on the city of Findlay — known as the Flag City USA for its extraordinary patriotic display of thousands of American flags each summer, and also as one of the most economically stable mid-sized cities in Ohio. Findlay sits atop vast oil and gas deposits that drove a spectacular "Findlay oil boom" in the 1880s, and energy heritage remains part of the city's identity. The county is home to Marathon Petroleum Corporation — one of the largest petroleum refining companies in the United States, headquartered in Findlay — and Whirlpool Corporation (major manufacturing operations). The University of Findlay (private liberal arts institution with exceptional equestrian and pre-veterinary programs) and Owens Community College (with a Findlay campus) provide education. The Findlay Reservoir and Riverbend Recreation Area offer recreation.
