 The culture of Delmarva is starkly different from the rest of the Mid-Atlantic region and is much like that of the Southern United States.While the northern portion of Delmarva, such as the Wilmington, Delaware metro area, is similar to the urban regions of Philadelphia, the Maryland and Virginia Delmarva counties (as well as the southern two counties in Delaware) are more conservative than their "mainland" counties.Delmarva is driven by agriculture and commercial fishing.
