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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic American Indian population in Idaho are found in zip codes corresponding to recognized tribal lands, most notably the Nez Perce Reservation area in north-central Idaho (appearing in teal shades around 10-20%) and the Fort Hall Reservation near Pocatello in the southeast, with a small cluster near the Coeur d'Alene Reservation in the northern panhandle. A striking yellow-green outlier on the western border in the central-north region suggests a zip code exceeding 25%, likely aligned with the Nez Perce tribal community near Lapwai. The vast majority of Idaho's zip codes register at or below 1%, creating a stark contrast between reservation-affiliated areas and the predominantly non-Native demographic composition across the rest of the state.
