Islandton, SC population, income and ZIP codes

Islandton CDP is a very small community in South Carolina, with 54 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #462 of 475 ranked by population — larger than 2% of them. The median age here is 71 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Islandton CDP earn a median of $38,250 a year, 51.3% below the national figure of $78,538 and 28% below the $53,071 median for the 263 South Carolina cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Islandton CDP is valued at $126,300, 58.4% below the national figure and 29% below the $177,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 54.3% 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 71 puts Islandton CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 54 residents, a handful of survey responses moves every median on this page. Compare Islandton CDP against its county rather than against national figures.

The Census withheld gross rent for Islandton CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
