How many counties does South Carolina have?
South Carolina has 46 counties covering 30,062 square miles and roughly 5,296,225 residents. The state was admitted to the Union in 1788 as the 8th state, and the current county boundaries reflect more than a century of administrative subdivision.
The largest county by land area is Horry County at 1,134 square miles, home to about 395,678 residents. The most populous is Greenville County with approximately 611,336 residents — a density of about 779 people per square mile.
At the other end of the scale, Allendale County has only about 8,090 residents.
South Carolina’s capital is Columbia, while the largest city is Charleston — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
