Delaware's Five Largest Cities by Population
Despite being the second-smallest U.S. state, Delaware's urban centers concentrate most of its population. Based on recent census data:
| Rank | City | Population |
| 1 | Wilmington | 70,843 |
| 2 | Dover | 36,047 |
| 3 | Newark | 31,454 |
| 4 | Middletown | 19,250 |
| 5 | Milford | 9,556 |
Key Context:
- Wilmington, the economic hub, contains ~7% of the state's total population (~1 million)
- Dover, the capital, is the second-largest but less than half Wilmington's size
- Newark hosts the University of Delaware, driving its growth
- Middletown has grown rapidly due to suburban expansion from Wilmington/Philadelphia
- Milford straddles Kent and Sussex counties, serving as a southern commercial center
Note: Population figures vary by census year and methodology (city proper vs. metropolitan area). These represent typical recent estimates for municipal boundaries.
