Full methodology ›The read
Duncan, South Carolina (ZIP 29334), on the composite measure, lands in the top 24% healthiest ZIPs nationally (7,619th) and the top 14.4% of South Carolina (60th).
Reading across the measures, this area's clearest strengths come through: modeled mammography stands in the top 2.6% nationally, lead in tap water is at the national minimum, and subsidized affordable housing rests in the top 8.8% nationally. Modeled hearing disability sits in the bottom 9.0% nationally, and coronary heart disease registers in the bottom 8.7% nationally. Distance to a community health center lands at the national minimum, shared with about 23% of ZIPs. By contrast, modeled industrial-pollution burden resides in the top 2.9% nationally, and slow internet speeds lies in the top 3.6% nationally. Modeled air-toxics cancer risk settles in the top 4.5% nationally, and distance to a Superfund site stands in the bottom 6.1% nationally.
Set against the neighboring ZIPs, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. In everyday language, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. A healthier neighbor overall sits at ZIP 29375, just across the boundary.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 1.09 years of 77.5, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match. How distance is measured
