Full methodology ›The read
Winchester, Idaho (ZIP 83555), on the composite measure, lands in the bottom 35% nationally (20,803rd) and the bottom 25% of Idaho (201st), based on limited data; treat as directional.
Where the data leans one way, another reading answers it: modeled loneliness sits in the bottom 4.1% nationally, and distance to a Superfund site registers in the top 6.8% nationally. Unemployment lands at the national minimum, shared with about 15% of ZIPs. Modeled pfas resides in the bottom 9.7% nationally. On the other hand, modeled hearing disability lies in the top 1.6% nationally, and fine-particle settles in the top 3.0% nationally. PFAS in drinking water stands at the national maximum, and distance to a nursing home is in the top 5.4% nationally. Walkability rests in the bottom 5.8% nationally. Fiber broadband sits at the national minimum, shared with about 19% of ZIPs.
In everyday language, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. A healthier neighbor overall sits at ZIP 83501, 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 1.27 years of 79.7, 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.
