Aiken, SC, United States

Capital City

Living costs run 8% below the U.S. average in this aging Southern city where nearly a third of residents are over 65. Not your typical retirement haven though - this former winter playground for Vanderbilts and Whitney's now orbits around a massive nuclear facility.

With 32,025 residents, Aiken balances its historic identity as an equestrian-focused winter colony with its modern role as a bedroom community for the Savannah River Site nuclear complex. The city's demographics skew older and female, with just 82 men for every 100 women and median age pushing 48. Despite its small-city status, it maintains an overwhelmingly urban character - 99.4% of residents live in urban areas.

Founded in 1835 as a railroad terminus, Aiken transformed into an unlikely blend of nuclear science and Southern gentility. Today's residents find a city where historic polo fields and the 2,100-acre Hitchcock Woods urban forest share space with a university campus and technical facilities. The housing market maintains a healthy 91% occupancy rate, though rental vacancies run higher at 8.3%. For budget-conscious retirees and nuclear industry workers, the median household income of $49,100 stretches further here than in many Southern cities.
