Gaffney, SC population, income and ZIP codes

Gaffney city is a mid-size town in South Carolina, with 12,612 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #49 of 475 ranked by population — larger than 89% of them. The median age here is 32.8 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Gaffney city earn a median of $41,214 a year, 47.5% below the national figure of $78,538 and 22% below 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 24.8% 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 Gaffney city is valued at $141,100, 53.5% below the national figure and 20% below the $177,100 peer median, while median gross rent runs $822 a month, 41.5% below the national figure, or roughly $9,864 across a full year. A household on the local median income would put about 23.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 54.2% 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.

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.
