Household Median Income by Zip Code (ZCTA5) — Delaware

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern Delaware, particularly the suburban zip codes between Wilmington and the Pennsylvania border, exhibits the highest household median incomes in the state, with several areas exceeding $125,000 and approaching $150,000. A stark contrast emerges in central and lower Delaware, where most zip codes fall in the $50,000–$80,000 range, with pockets near Dover and certain southern coastal areas dipping below $40,000. Notably, the southeastern coastal region around the Rehoboth Beach area shows moderately elevated incomes compared to surrounding rural zip codes, likely reflecting retirement and vacation-home wealth effects.
