Dorchester ZIP codes — Dorchester County, South Carolina

Dorchester County is a mid-size city in South Carolina, with 164,322 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 37.9 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 Dorchester County earn a median of $76,896 a year, 2.1% 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 11.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Dorchester County is valued at $294,400, 3% below the national figure, while median gross rent runs $1,381 a month, 1.8% below the national figure, or roughly $16,572 across a full year. A household on the local median income would put about 21.6% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 75.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
