Richland ZIP codes — Richland County, South Carolina

Richland County is a mid-size city in South Carolina, with 418,725 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 34.2 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Richland County earn a median of $61,699 a year, 21.4% below the national figure of $78,538. 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 16.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Richland County is valued at $224,200, 26.1% below the national figure, while median gross rent runs $1,185 a month, 15.7% below the national figure, or roughly $14,220 across a full year. A household on the local median income would put about 23% 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 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 60.4% 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.
