Population Non-Hispanic American Indian % by Zip Code (ZCTA5) — Arizona

NOTE: Gray indicates insufficient data or a suppressed estimate.

The northeastern quadrant of Arizona exhibits overwhelmingly high Non-Hispanic American Indian population percentages, frequently exceeding 50% and approaching 100% in many zip codes, corresponding to the Navajo Nation, Hopi Reservation, and adjacent tribal lands. The Phoenix and Tucson metropolitan areas display consistently low percentages, generally below 3%, with scattered zip codes in the 1–5% range likely reflecting urban Indigenous communities near reservation borders. A notable contrast exists along the western and southwestern corridors, where percentages remain minimal, while isolated pockets of moderate concentration (10–25%) appear in central Arizona near communities such as the Salt River and Gila River reservations.
