This page is the City map of Delaware, a map with streets, paths, and places across the state in the United States. Delaware covers approximately 6,452 square kilometres and had 989,948 residents in 2020, up from 897,934 in 2010. The state was founded in 1787 and occupies the Delmarva Peninsula between Maryland, Pennsylvania, and New Jersey, with coastlines along Delaware Bay and the Atlantic Ocean. Its landscape includes the Delaware River, the Brandywine Creek, the coastal plain, and the Cape Henlopen area, while the state’s average elevation is recorded at about 18 metres. Delaware contains three counties and includes the mapped subregions Clayton, Smyrna, New Castle County, Kent County, and Sussex County; documented long-distance cycling routes include the East Coast Greenway and the 9-11 Trail.

Clayton is a town in Delaware located primarily in Kent County, with its built-up area connected to the central Delaware settlement pattern around Smyrna and Dover. The town lies near the Delaware Route 6 corridor and is served by local roads linking it with Kent County communities. Clayton’s position in central Delaware places it within the state’s gently rolling coastal plain rather than the Atlantic shore. The nearby St. Jones River and Murderkill River drainage basins are characteristic waterways of the central part of the state.
