Delaware statistical areas

The U.S. currently has four statistical areas that have been delineated by the Office of Management and Budget (OMB). On July 21, 2023, the OMB delineated one combined statistical area, two metropolitan statistical areas, and one micropolitan statistical area in Delaware. As of 2023, the largest statistical area in the state is the Philadelphia-Reading-Camden, PA-NJ-DE-MD Combined Statistical Area, which includes Delaware's largest city, Wilmington.

Primary statistical areas
Primary statistical areas (PSAs) include all combined statistical areas and any core-based statistical area that is not a constituent of a combined statistical area. Of the four statistical areas of Delaware, two are PSAs comprising one combined statistical area and one micropolitan statistical area.
