ZIP code 29420

ZIP 29420 is a mid-size town in Dorchester County, South Carolina, with 23,311 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #80 of 424 ranked by population — larger than 81% of them. The median age here is 35.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 29420 earn a median of $69,043 a year, 12.1% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 14.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 29420 is valued at $283,900, 6.4% below 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 26.2% 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 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 62.6% 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.

South Carolina charges 6% statewide, and local governments overlapping 29420 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 29420 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.
