U.S. Citizens (% of Population Over 18) by Zip Code (ZCTA5) — Hawaii

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes on the Big Island's Kona coast and portions of central Oahu display notably lower U.S. citizenship rates among adults, dropping to around 75–80%, likely reflecting concentrations of non-citizen workers in tourism and agricultural sectors. Rural areas across Kauai, Molokai, and the Big Island's southern districts generally report higher citizenship percentages, frequently exceeding 95%, consistent with longer-established resident populations. Maui exhibits a sharp internal contrast, with western resort-area zip codes showing markedly lower rates compared to the island's more residential eastern and upcountry communities.
