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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Concentrated clusters of Non-Hispanic American Indian population appear in northern Wisconsin—particularly in the northwest near Bayfield and Sawyer counties and in the northeast near Menominee County, where several zip codes exceed 25-50% and align with established tribal reservation boundaries including the Bad River, Lac Courte Oreilles, and Menominee reservations. A notable central cluster around Shawano and Wood counties corresponds to the Stockbridge-Munsee and Ho-Chunk Nation communities, with one zip code reaching near 100%. The vast majority of southern and eastern Wisconsin zip codes register below 1%, creating a stark geographic contrast between reservation-adjacent areas and the rest of the state.
