Sun City is included within the Hilton Head Island-Bluffton-Beaufort, SC Metropolitan Statistical Area.

Del E. Webb Construction Company was acquired by PulteGroup in 2001 and began development of the Jasper County portions that same decade.

A new golf course, Argent Lakes, and amenity center opened in the Hardeeville area of Sun City in 2014.

The majority of the residents are married and retired, though some continue to work full-time or part-time or have home-based businesses.

A bridge connects the Beaufort and Jasper county portions of the community over US 278, thus avoiding the need to enter and exit through multiple gates and cross the heavily traveled highway.

Sun City contracts with a security provider that patrols the neighborhood and some of the gate entrances.
