NOTE: Gray indicates insufficient data or a suppressed estimate.
Larger household sizes of 3.0 or above cluster in the suburban and exurban zip codes ringing the Greenville-Spartanburg corridor in the Upstate and in several rural Pee Dee region zip codes in the northeast, while the smallest households—often below 2.0—concentrate in downtown Charleston, parts of the Lowcountry coast, and scattered zip codes near Columbia likely associated with college student populations or retirement communities. A broad swath of the Midlands and rural interior maintains moderate averages between 2.4 and 2.8, with notable pockets of higher values appearing in fast-growing suburban areas south of Charlotte near Fort Mill and Lake Wylie. The coastal zone displays significant variability, with resort and retirement-oriented communities like Hilton Head and Kiawah registering markedly lower household sizes compared to adjacent inland zip codes.
