The Digital Divide in South Carolina
Rural and low-income communities in South Carolina often have only one or two broadband providers — and in some cases, none offering speeds that meet the FCC's 100/20 Mbps benchmark. This lack of competition leads to higher prices and slower speeds compared to urban areas.
Federal programs like BEAD (Broadband Equity, Access, and Deployment), the Affordable Connectivity Program successor, and USDA ReConnect grants are directing billions toward closing these gaps. You can check whether your area qualifies for subsidized broadband by entering your ZIP code in our availability checker.
How This Data Is Compiled
We track cities using U.S. Census population estimates and cross-reference them with FCC BDC filings. Smaller population centers are more likely to be underserved because providers prioritize areas with higher subscriber density. For our full methodology, see the methodology page.
