The read
Judged by its overall standing, Port Wentworth, Georgia (ZIP 31407) sits in the top 38% healthiest ZIPs nationally (12,092nd) and the top 27% of Georgia (193rd).
The measures that most flatter this area set the tone for the rest: modeled high cholesterol stands in the bottom 2.9% nationally, coronary heart disease resides in the bottom 2.7% nationally, and hearing disability sits in the bottom 2.6% nationally. Against that, modeled disaster risk stands in the top 5.1% nationally, loneliness resides in the top 5.3% nationally, and short sleep sits in the top 6.1% nationally. Modeled humid heat stands in the top 5.9% nationally, and floodplain exposure resides in the top 6.2% nationally. Homeownership sits in the bottom 8.3% nationally, and outer-floodplain exposure stands in the top 8.9% nationally.
Placed beside its immediate neighbors, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. Put plainly, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". A healthier nearby ZIP overall is ZIP 31312, 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 0.45 years of 77.2, 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
