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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Wind River Indian Reservation in west-central Wyoming dominates the map with zip codes exceeding 50–100% Non-Hispanic American Indian population, forming the state's most prominent concentration in Fremont County. Outside this cluster, nearly all zip codes across Wyoming fall below 3%, with the vast majority registering at or near 0%, reflecting the highly localized nature of the American Indian population. A slight elevation in percentages is visible in a few southeastern zip codes near the Colorado border, though these remain well below 5%.
