Fairfield ZIP codes — Fairfield County, South Carolina

Fairfield County is a mid-size town in South Carolina, with 20,741 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 46.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Fairfield County earn a median of $46,972 a year, 40.2% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 16.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Fairfield County is valued at $129,100, 57.4% below the national figure, while median gross rent runs $910 a month, 35.3% below the national figure, or roughly $10,920 across a full year. A household on the local median income would put about 23.2% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 76% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
