Household Median Income by Zip Code (ZCTA5) — South Carolina

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest household median incomes in South Carolina concentrate in the suburban zip codes ringing Charlotte along the northern border, the Greenville-Spartanburg upstate corridor, and the coastal resort communities near Hilton Head Island and Kiawah, where several zip codes exceed $125,000. A pronounced low-income band stretches through the rural Midlands and Pee Dee regions—particularly in the corridor from Orangeburg through Williamsburg and Marion counties—where median incomes frequently fall below $30,000, reflecting the state's persistent "Corridor of Shame" economic disparities. The Charleston metro area displays sharp intra-urban contrasts, with affluent Mount Pleasant and Daniel Island zip codes sitting adjacent to significantly lower-income areas within the city proper and North Charleston.
