Lexington County, South Carolina is a county located in the central part of the state, forming part of the Columbia metropolitan area. Its county seat is the town of Lexington, though a significant portion of the state capital, Columbia, extends into the county. Established in 1804 from parts of Orangeburg District and named for the Battle of Lexington, it has evolved from an agricultural region into a major suburban and economic hub.

History

The area was originally inhabited by the Congaree and other indigenous groups before European settlement. Following the American Revolutionary War, the county was officially formed in 1804, with its early economy centered on plantation agriculture, particularly cotton, reliant on enslaved labor. During the American Civil War, the region saw activity, including the passage of General Sherman's forces during the Carolinas Campaign. The late 19th and early 20th centuries were marked by the expansion of the railroad, connecting towns like Batesburg-Leesville and West Columbia to broader markets. The 20th century brought transformative projects like the construction of Lake Murray by the Lexington Water Power Company and the post-World War II growth of suburban communities around Columbia.

Geography

According to the United States Census Bureau, the county has a total area of 758 square miles, with Lake Murray forming a significant portion of its water area. The county lies within the Sandhills and Piedmont regions, with the Congaree River and Saluda River forming parts of its boundaries. Major waterways include the Broad River and the Twelve Mile Creek. The county contains parts of the Congaree National Park and is adjacent to Fort Jackson. Notable incorporated communities include Cayce, Irmo, and Springdale.

Demographics

As of the 2020 United States census, the population was 293,991, making it one of the most populous counties in the state. The racial makeup was predominantly non-Hispanic white and African American, with growing Hispanic and Asian communities. The county has experienced consistent population growth, driven by its proximity to Columbia and major employers like Fort Jackson and University of South Carolina. Significant population centers include the Columbia suburbs of West Columbia and the Lake Murray area.

Economy

The economy is diverse, with major sectors including manufacturing, healthcare, retail, and government services. Key employers and institutions are Prisma Health, the Lexington Medical Center, and the University of South Carolina system. The presence of Fort Jackson, the U.S. Army's largest Basic Combat Training site, is a significant economic driver. Industrial operations are supported by companies like International Paper and Amazon, which have major facilities in the county. Lake Murray also supports a substantial tourism and recreation industry.

Government and politics

The county operates under a council-administrator form of government, with an elected Lexington County Council and a county administrator. It is part of the Eleventh Judicial Circuit and is represented in the South Carolina Senate and South Carolina House of Representatives. Federally, portions of the county lie within the 2nd and 3rd congressional districts, historically represented by figures like Joe Wilson and Jeff Duncan. The county has traditionally voted for Republican candidates in recent presidential elections.

Education

Public education is managed by Lexington County School District One and Lexington County School District Two, which operate numerous high schools such as Lexington High School and River Bluff High School. The county is also served by the Lexington County Career and Technology Center. Higher education institutions include a major campus of Midlands Technical College and proximity to the University of South Carolina in Columbia. Private schools like Hammond School and Ben Lippen School also operate within the county.
