South Carolina county geography overview

South Carolina has 46 counties, which places it 31st among the 50 state and District of Columbia maps in this atlas when ordered by number of county-level units. Their combined 30,064.5 square miles of land place the state 40th by mapped land area.

The average county-level area is 654 square miles, while the median is 617 square miles. The median is often the better description of a typical unit because one or two very large areas can pull the average upward. The five largest units together account for about 18% of the state’s mapped land area.

Alphabetical list of South Carolina counties

The table is alphabetical, so it works as a name and FIPS-code reference rather than an area ranking. Every identifier begins with the South Carolina state FIPS prefix 45. Land and water figures are rounded to one decimal place.

How to read and use this map

County lines are administrative boundaries, not postal routes. A mailing address can use a city name associated with a neighboring area, and ZIP codes can cross county lines. When you need to identify a county for an address, confirm it with an official geocoder or local government source.

For classroom or planning use, download a PDF from the controls above. Labelled exports use numbered callouts for crowded areas; numbered quiz maps match the alphabetical county list. SVG files keep the boundary lines sharp at larger paper sizes.
