ZIP code 29456

ZIP 29456 is a small city in Charleston County, South Carolina, with 39,280 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #35 of 424 ranked by population — larger than 91% of them. The median age here is 31.9 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 ZIP 29456 earn a median of $79,038 a year, essentially level with 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 9.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 29456 is valued at $244,400, 19.4% below the national figure, while median gross rent runs $1,473 a month, 4.8% above the national figure, or roughly $17,676 across a full year. A household on the local median income would put about 22.4% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62.7% 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.

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.

ZIP 29456 is tabulated inside Charleston County, South Carolina, one of 26 ZIP areas the Census publishes for that county and 424 across South Carolina. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 29456 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 29456 reports a median household income of $79,038, 6% below the $84,531 county median, and 38% above the $57,227 typical SC ZIP. Owner-occupied homes are valued at a median of $244,400, 46% below the county figure and 47% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,473 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

South Carolina charges 6% statewide, and local governments overlapping 29456 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 29456 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
