State Profile
Delaware — neighborhoods by ZIP code
Delaware spans 3 counties and approximately 96 active ZIP code tabulation areas, home to roughly 994,084 residents according to the most recent American Community Survey 5-Year Estimates from the U.S. Census Bureau.
The pages below break the state down city by city, then ZIP code by ZIP code. Each ZIP profile covers demographics, cost of living indicators (median income, median home value, and median rent), and the surrounding neighborhoods within roughly 30 miles. Use this as a starting point — not a substitute — when researching a move, planning a trip, or just trying to understand how different parts of Delaware compare.
Statewide, the median household income across these ZIPs averages out to roughly $52,114, with a typical owner-occupied home valued near $214,452. Those numbers conceal a wide range — some ZIP codes here have median incomes more than triple the state average, while rural ZIPs in the same state can sit far below it. The city and ZIP-level breakdowns below show where those differences land geographically.
