Seabrook, SC population, income and ZIP codes

Seabrook CDP is a very small community in South Carolina, with 959 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #272 of 475 ranked by population — larger than 42% of them. The median age here is 54.6 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 Seabrook CDP earn a median of $62,941 a year, 19.9% below the national figure of $78,538 and 19% above 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 18% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Seabrook CDP is valued at $27,200, 91% below the national figure and 85% below the $177,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 0.4×, 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. 90.2% 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.

A median age of 54.6 puts Seabrook 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 959 residents, a handful of survey responses moves every median on this page. Compare Seabrook CDP against its county rather than against national figures.

The Census withheld gross rent for Seabrook 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.
