Among the 30 largest places in Delaware, Wilmington has the most residents (71,727), followed by Dover and Newark. Click any column to sort; click a city for its guide.
Across the 30 places in Delaware that we cover, the median is 7,834 and the average 12,670; the figure runs from 71,727 (Wilmington) to 3,505 (Lewes). That is a spread of 20.5 times between the two ends.
The first five are Wilmington, Dover, Newark, Middletown, Bear. A high or low position is not good or bad on its own: size brings more employers and services but also longer commutes and more competition for housing. Use the Compare tab on each city page to see how two places differ across income, rent, commute and education, and check the county page for the local job market.
