ZIP 29518 in context

How this area compares with national benchmarks.

ZIP 29518 is a very small community in Williamsburg County, South Carolina, with 913 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #358 of 424 ranked by population — larger than 15% 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. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 29518 earn a median of $43,214 a year, 45% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 19.4% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in ZIP 29518 is valued at $151,100, 50.2% below the national figure, while median gross rent runs $930 a month, 33.9% below the national figure, or roughly $11,160 across a full year. A household on the local median income would put about 25.8% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 913 residents, a handful of survey responses moves every median on this page. Compare ZIP 29518 against its county rather than against national figures.

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.

Reading ZIP 29518 in context

How 29518 sits inside Williamsburg County and South Carolina.

ZIP 29518 is tabulated inside Williamsburg County, South Carolina, one of 7 ZIP areas the Census publishes for that county and 424 across South Carolina. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 29518 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 29518 reports a median household income of $43,214, close to the $43,301 county median, and 24% below the $57,227 typical SC ZIP. Owner-occupied homes are valued at a median of $151,100, 75% above the county figure and 9% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $930 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 29518 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 29518 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.
