What these numbers say together
Islandton, SC (ZIP 29929) sits in Colleton County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: High Blood Pressure comes in above the national average at 43.2%. No NCES schools are mapped to this ZIP in the current dataset. 2 colleges and universities serve the area, with median in-state tuition of $8,443. 22% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. BLS QCEW reports average annual pay of $48,150 per worker, roughly 26% below the US average. FEMA has issued 28 federal disaster declarations affecting this ZIP since 1989 — a high-frequency exposure profile. County Health Rankings reports 17,986 years of potential life lost per 100,000 (2025) — well above the national county median. 38.0% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. South Carolina levies a graduated state income tax (top rate 6.20%); a household at the local median AGI of $49,327 would pay roughly $1,835/year before deductions. IRS migration data (2022-2023) shows a net gain of 267 residents (162 households) — the ZIP's primary county is growing. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $56,170, fair market rent of $1,170 for a two-bedroom, and a typical home value of $182,676, down 3.3% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 22.1%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
