Delaware occupies the northeastern portion of the Delmarva Peninsula and some islands and territory within the Delaware River. It is the second smallest and sixth least populous state, but the sixth most densely populated. Delaware’s largest city is Wilmington. The state is divided into three counties, the lowest number of any state. From north to south, they are New Castle County, Kent County, and Sussex County. While the southern two counties have historically been predominantly agricultural, New Castle County is more industrialized.
