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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of South Carolina zip codes have Non-Hispanic American Indian populations below 1%, with the state displaying a predominantly uniform dark purple shading across most regions. A notable exception appears in the northeastern coastal area near the North Carolina border—likely in the Dillon and Marlboro county region—where one zip code reaches approximately 50% or higher, likely reflecting the presence of the Lumbee or Pee Dee tribal communities. Scattered zip codes with slightly elevated percentages (1–3%) appear in the Midlands, Lowcountry, and a few upstate areas, though these remain isolated rather than forming any broader regional cluster.
