Olympia, SC population, income and ZIP codes

Olympia CDP is a small town in South Carolina, with 1,301 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #237 of 475 ranked by population — larger than 50% 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 Olympia CDP earn a median of not published a year. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 86.2% 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 Olympia CDP is valued at $189,200, 37.6% below the national figure and 7% above the $177,100 peer median, while median gross rent runs $1,214 a month, 13.7% below the national figure, or roughly $14,568 across a full year. 17.3% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

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.

The Census withheld household income for Olympia 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.
