Socastee is a residential community located inland between Highway 17 and the Waccamaw National Wildlife Refuge. It lies along the Intracoastal Waterway, adjacent to the Market Common, near the junction of Highways 544 and 707. As of the 2010 census, the population of Socastee hovered just below 20,000.
The unincorporated community is comprised of neighborhoods of large, single-family homes, town houses, and multi-family complexes. The area is home to some of the most affordable waterfront real estate along the Grand Strand— featuring homes with private docks along the Intracoastal Waterway.
The expansion of Highway 31 to Highway 544 has made Socastee more accessible to other areas along the beach, and has inspired an increase in development of the town. Socastee has its own elementary, middle and high schools which are part of the Horry County school system, as well as parks and recreation facilities and a library. It is an historic town that features a still-functioning swing bridge that crosses the Intracoastal Waterway; the bridge was built in 1935.
