Allendale, SC population, income and ZIP codes

Allendale town is a small town in South Carolina, with 2,595 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #164 of 475 ranked by population — larger than 65% of them. The median age here is 36.9 years against 39.1 nationally, a slightly younger 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 Allendale town earn a median of $25,250 a year, 67.8% below the national figure of $78,538 and 52% below the $53,071 median for the 263 South Carolina cities we cover. 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 42.8% 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 Allendale town is valued at $65,300, 78.5% below the national figure and 63% below the $177,100 peer median, while median gross rent runs $685 a month, 51.3% below the national figure, or roughly $8,220 across a full year. A household on the local median income would put about 32.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 59% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Allendale town is the unusual combination of expensive to rent and cheap to buy: rent takes 32.6% of median income while homes cost only 2.6× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price.
