% of Households with Broadband Internet, by Zip Code (ZCTA5) — South Carolina

NOTE: Gray indicates insufficient data or a suppressed estimate.

Broadband adoption rates across South Carolina reveal a pronounced urban-rural divide, with zip codes in the Charlotte metro spillover area (Rock Hill/Fort Mill), the Greenville-Spartanburg corridor, and suburban Columbia consistently reaching 85–95%+ coverage, while rural zip codes in the Pee Dee region, parts of the Lowcountry, and the I-95 corridor frequently fall below 65%. A cluster of particularly low-connectivity zip codes is visible in the southeastern interior around Allendale, Hampton, and Williamsburg counties, forming a contiguous band of digital disadvantage. Coastal zip codes near Charleston, Hilton Head, and Myrtle Beach generally perform well, though pockets of lower adoption persist in adjacent rural areas just inland from the coast.
