Top 77 Cities in Delaware by Population

Because Delaware has one of the lowest populations in the entire United States (it is ranked as the 45th most populous), most of its cities have smaller populations. In fact, the state doesn’t have any cities that have populations that exceed 100,000 residents. The state’s largest city, Wilmington, is approaching 72,000 residents according to data from 2016. The next largest city, Dover, has a little more than half of that, with over 37,000 residents. Dover is also the state capital.

Delaware, as one of the nation’s smallest states by area coming in only behind Rhode Island, only has a total of 57 incorporated areas, which includes cities, towns and villages. The state is divided into three counties. Hartly is the smallest incorporated town, with a population of just 74 people. The town itself is just 0.06 square miles. The state has multiple incorporated areas that have populations of less than 1,000 people. Dover, the second most populated city, is the largest in terms of area, stretching across over 23 square miles.
