Philadelphia County, Pennsylvania
Philadelphia is both a city and a county, coterminous since 1854 and packed into 134 square miles between the Delaware and Schuylkill rivers, from Center City to the rowhouse Northeast. Hospitals and universities drive employment, with life sciences expanding at University City's Schuylkill Yards and the Navy Yard's 1,200-acre redevelopment; because city and county are one, a single zoning code governs every site.
