Population Non-Hispanic White % by Zip Code (ZCTA5) — Delaware

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern Delaware, particularly the Wilmington metropolitan area, exhibits the greatest demographic diversity, with several zip codes falling below 40% non-Hispanic white population, likely corresponding to the city of Wilmington itself and surrounding urban communities. The southern and western portions of Kent and Sussex counties trend notably higher, with many rural zip codes exceeding 80% non-Hispanic white population, creating a clear north-south gradient across the state. A secondary cluster of lower non-Hispanic white percentages appears in central Sussex County, potentially around the Georgetown and Seaford areas, contrasting with the predominantly yellow-green coastal zip codes in the Rehoboth Beach and Bethany Beach corridor.
