Summerville town, SC in context
How this area compares with national benchmarks.
Summerville town is a small city in South Carolina, with 51,262 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #7 of 475 ranked by population — larger than 98% of them. The median age here is 38.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.
Households in Summerville town earn a median of $78,621 a year, essentially level with the national figure of $78,538 and 48% above the $53,071 median for the 263 South Carolina cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 10.3% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Summerville town is valued at $295,700, 2.5% below the national figure and 67% above the $177,100 peer median, while median gross rent runs $1,414 a month, essentially level with the national figure, or roughly $16,968 across a full year. A household on the local median income would put about 21.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 68% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
