Gilbert, SC population, income and ZIP codes

Gilbert town is a very small community in South Carolina, with 563 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #327 of 475 ranked by population — larger than 31% of them. The median age here is 40.3 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Gilbert town earn a median of $76,364 a year, 2.8% below the national figure of $78,538 and 44% 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 5.3% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Gilbert town is valued at $239,100, 21.2% below the national figure and 35% above the $177,100 peer median, while median gross rent runs $980 a month, 30.3% below the national figure, or roughly $11,760 across a full year. A household on the local median income would put about 15.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.2% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 563 residents, a handful of survey responses moves every median on this page. Compare Gilbert town against its county rather than against national figures.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
