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 also the sixth-most densely populated. Delaware's largest city is Wilmington, while the state capital is Dover, the second-largest city in the state. The state is divided into three counties, having 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 is more urbanized. In a similar vein to Maryland, Delaware's geography, culture, and history combine elements of the Mid-Atlantic, Northeastern, and Southern regions of the country.
