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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic American Indian population are clustered in the northwestern portion of the state, corresponding to the Pine Ridge and Rosebud reservations in Sheridan, Dawes, and surrounding counties, where several zip codes exceed 25–50%. A notable secondary cluster appears in the northeastern part of the state near Thurston County, where the Omaha and Winnebago reservations drive zip codes to near 100% representation, visible as the bright yellow area along the eastern border. The vast majority of central and southern Nebraska zip codes fall below 1%, creating a stark demographic contrast between reservation-adjacent areas and the remainder of the state.
