Alcolu, SC population, income and ZIP codes

Alcolu CDP is a very small community in South Carolina, with 426 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #350 of 475 ranked by population — larger than 26% of them. The median age here is 21.8 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Alcolu CDP earn a median of $41,917 a year, 46.6% below the national figure of $78,538 and 21% below 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 44.4% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Alcolu CDP is valued at $166,400, 45.2% below the national figure and 6% below the $177,100 peer median, while median gross rent runs $685 a month, 51.3% below the national figure, or roughly $8,220 across a full year. A household on the local median income would put about 19.6% 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 4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 62.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 21.8 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 426 residents, a handful of survey responses moves every median on this page. Compare Alcolu CDP against its county rather than against national figures.

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.
