Population Non-Hispanic Black % by Zip Code (ZCTA5) — South Dakota

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of South Dakota zip codes have near-zero Non-Hispanic Black population percentages, reflected in the dominant dark purple shading across the state. A notable exception appears in the northeastern region, where a single zip code—likely encompassing part of the Watertown or Aberdeen area—registers approximately 25-30%, representing the highest concentration visible on the map. Modest but discernible elevations in the 5-10% range appear in zip codes associated with Sioux Falls in the southeast and the Pierre/central corridor area, consistent with the state's limited urban centers serving as primary destinations for Black residents.
