White Knoll, SC population, income and ZIP codes

White Knoll CDP is a mid-size town in South Carolina, with 7,865 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #77 of 475 ranked by population — larger than 83% of them. The median age here is 31.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 White Knoll CDP earn a median of $79,531 a year, 1.3% above the national figure of $78,538 and 50% above the $53,071 median for the 263 South Carolina cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 6.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in White Knoll CDP is valued at $232,000, 23.5% below the national figure and 31% above the $177,100 peer median, while median gross rent runs $1,269 a month, 9.7% below the national figure, or roughly $15,228 across a full year. A household on the local median income would put about 19.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.1% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
