Charleston County, SC in context
How this area compares with national benchmarks.
Charleston County is a mid-size city in South Carolina, with 414,711 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 39 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 Charleston County earn a median of $84,320 a year, 7.4% above 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 11.6% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Charleston County is valued at $450,800, 48.6% above the national figure, while median gross rent runs $1,506 a month, 7.1% above the national figure, or roughly $18,072 across a full year. A household on the local median income would put about 21.4% 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 5.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 63.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.
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.

How to read this page
What these estimates cover.
Figures are five-year rolling averages from the American Community Survey, not single-year counts, so they describe conditions across 2019-2023 ACS 5-year rather than a single date. Median home value covers owner-occupied units as valued by their owners, and median gross rent includes utilities the renter pays. Small counties carry wide margins of error; treat single-dollar differences between neighbouring counties as noise.
