% of Population on Food Stamps or SNAP (Last 12 Months), by Zip Code (ZCTA5) — Delaware

NOTE: Gray indicates insufficient data or a suppressed estimate.

Wilmington-area zip codes in northern New Castle County exhibit the highest SNAP participation rates in the state, with at least one zip code exceeding 50% and several surrounding areas in the 25–35% range, reflecting concentrated urban poverty. In contrast, suburban zip codes in southern New Castle County and much of central Kent County generally fall in the 5–15% range, while Sussex County in the south displays a more mixed pattern with pockets of elevated SNAP usage (~15–25%) interspersed among lower-participation coastal and rural areas. The starkest contrast exists between the deep purple zip codes near the northern Delaware coast and Brandywine Valley—indicating minimal SNAP reliance below 5%—and the yellow-highlighted urban core just miles away.
