South Carolina’s 46 counties, by the numbers

Every county’s population, median household income, unemployment, density, and land area — sortable by any column, so you can find yours or rank by what matters to you. A few patterns run through the data:

  • Concentrated. Half of South Carolina’s 5,373,555 residents live in just 7 of 46 counties, and the five largest hold 40.2% of the total. Census PEP 2023
  • Income tracks poverty. The gap from richest to poorest runs 2.5×, and the 10 highest-income counties average 11.0% in poverty against 25.6% for the 10 lowest. Census SAIPE 2023
  • Mostly small. Half of South Carolina’s counties have fewer than 59,565 residents, and half report a median household income below $57,547 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
  • Lopsided density. Only 13 of 46 counties are denser than South Carolina’s statewide average of 179 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
