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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern Delaware, particularly the zip codes in and around Wilmington and Newark in New Castle County, exhibits the highest concentrations of Non-Hispanic Asian residents, with several zip codes reaching 10–25% or higher, likely reflecting proximity to corporate employers, universities, and established immigrant communities. The contrast with southern Delaware is stark, as Kent and Sussex County zip codes overwhelmingly fall below 2%, with only a few scattered areas around Dover showing slightly elevated percentages in the 2–5% range. This north-south gradient underscores a demographic pattern where Asian population presence is heavily concentrated in the urbanized, economically diversified corridor of the state's northernmost county.
