What percentage of South Carolina residents have access to fiber internet?

Just over 37% of SC residents have access to fiber broadband. There are only 10 fiber broadband providers in the state.

This is a significant issue in the state and affects its poorest counties, Cherokee, Union, and Abbeville Counties, most. South Carolina also has the country’s lowest rates of broadband uptake by low-income households.

What is the State of South Carolina doing to improve internet access?

The Office of the Govenor has commissioned the Connect South Carolina initiative to improve broadband access and adoption in the state. This non-profit is working to audit broadband coverage in each SC community for a more detailed picture of the current state of broadband adoption in South Carolina.
