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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Eastern Oklahoma exhibits markedly higher Non-Hispanic American Indian population concentrations, with numerous zip codes in the 15–50% range and several exceeding 50%, reflecting the historical boundaries of Indian Territory and the concentration of tribal nations such as the Cherokee, Choctaw, and Creek. The western half of the state, particularly the Panhandle and southwestern counties, shows consistently low percentages at or below 3%, creating a stark east-west demographic divide. Notable clusters of elevated percentages also appear in south-central Oklahoma around areas associated with the Chickasaw and Choctaw nations, while urban cores like Oklahoma City display lower concentrations compared to their surrounding rural and suburban zip codes.
