South Williamson, KY population, income and ZIP codes

South Williamson CDP is a very small community in Kentucky, with 301 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #420 of 554 ranked by population — larger than 24% of them. The median age here is 55.9 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 South Williamson CDP earn a median of $116,027 a year, 47.7% above the national figure of $78,538 and 109% above the $55,469 median for the 246 Kentucky 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 26.6% 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 South Williamson CDP is valued at $167,400, 44.8% below the national figure and 6% above the $157,200 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.4×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 72.9% 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.

A median age of 55.9 puts South Williamson 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. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

The Census withheld gross rent for South Williamson 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.
