St. Charles, SC population, income and ZIP codes

St. Charles CDP is a very small community in South Carolina, with 94 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #447 of 475 ranked by population — larger than 5% of them. The median age here is 73.8 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 St. Charles CDP earn a median of $31,515 a year, 59.9% below the national figure of $78,538 and 41% below 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 5.3% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in St. Charles CDP is valued at $260,900, 14% below the national figure and 47% above the $177,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 8.3×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 100% 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.

Home values sit at 8.3× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. A median age of 73.8 puts St. Charles 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.

The Census withheld gross rent for St. Charles 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.
