Franklin County is the main administrative, economic and population centre of Central Ohio. It contains Columbus, the state capital and largest city in Ohio, along with major suburban cities, townships, villages, employment districts and unincorporated communities.
Columbus is the county seat and the primary location for county government, courts, healthcare systems and regional institutions. Other important communities include Dublin, Grove City, Hilliard, Gahanna, Reynoldsburg, Westerville, Upper Arlington, Whitehall, Worthington, Bexley and Grandview Heights.
Franklin County government operates separately from the City of Columbus and other municipalities.
