Franklin County is Ohio's most populous county and one of the fastest-growing major counties in the United States, home to the state capital Columbus — Ohio's largest city and a genuine 21st-century economic powerhouse. Columbus has defied the population and economic decline that has afflicted much of the Rust Belt, growing consistently for decades driven by government, education, healthcare, technology, and finance. The Ohio State University — with over 60,000 students, one of the largest universities in the country — is the dominant employer and cultural institution. Other major corporate presences include Nationwide Insurance, Victoria's Secret, Bath & Body Works, Big Lots, Cardinal Health, Huntington Bancshares, and Abercrombie & Fitch. The county is home to the Columbus Zoo and Aquarium, Short North Arts District, German Village, Columbus Museum of Art, and several professional sports teams including the Columbus Blue Jackets (NHL) and Columbus Crew (MLS).
