Married Couple (% of all Households) by Zip Code (ZCTA5) — Delaware

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern Delaware's urbanized areas around Wilmington display the lowest married-couple household rates, with several zip codes falling below 30%, reflecting the city's higher concentration of single-person and non-family households. Suburban zip codes ringing Wilmington and extending into central New Castle County exhibit markedly higher rates in the 60–80% range, creating a sharp urban-suburban gradient. Southern Delaware presents a more mixed pattern, with coastal and resort-area zip codes near Rehoboth Beach showing notably lower rates compared to the predominantly rural inland areas of Kent and Sussex counties, which generally cluster in the 50–65% range.
