Full methodology ›The read
Ladson, South Carolina (ZIP 29456) ranks in the top 29% healthiest ZIPs nationally (9,333rd) and the top 18% of South Carolina (74th).
Several signals sit on each side of the ledger here: modeled coronary heart disease is in the bottom 6.3% nationally, and hearing disability registers in the bottom 7.2% nationally. Modeled radon lies in the bottom 2.3% nationally, and high cholesterol is in the bottom 7.9% nationally. Working the other way, modeled expected annual loss registers in the top 1.8% nationally, modeled disaster risk lies in the top 4.7% nationally, and PFOA in drinking water is in the top 7.8% nationally. PFOS in drinking water registers in the top 8.0% nationally, modeled humid heat lies in the top 8.9% nationally, and modeled industrial-pollution burden is in the top 11.2% nationally.
Against its neighbors, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. For context, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. The closest ZIP that ranks healthier overall is ZIP 29483, 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 1.05 years of 78.5, 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
