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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The northwestern Upstate region of South Carolina exhibits the highest concentrations of non-Hispanic white population, with many zip codes in the Greenville-Spartanburg corridor exceeding 80%, while a distinct band of low-percentage zip codes (below 30%) stretches through the central Midlands and Pee Dee regions, corresponding to historically majority-Black communities along the I-77 and I-95 corridors. The coastal Lowcountry presents a notably mixed pattern, with affluent beach communities like those near Hilton Head and Mount Pleasant showing moderate-to-high white percentages adjacent to zip codes in the Charleston and Beaufort areas with significantly lower shares. Sharp contrasts are particularly visible around Columbia, where predominantly white suburban zip codes directly border urban and rural zip codes with non-Hispanic white populations below 20%.
