Full methodology ›The read
By its overall health score, Irwin, Idaho (ZIP 83428) lands in the top 13.6% healthiest ZIPs nationally (4,358th) and the top 4.2% of Idaho (11th), based on limited data; treat as directional.
The measures split the difference for this area: modeled loneliness rests in the bottom 0.7% nationally, and distance to a hazardous-chemical facility is in the top 1.8% nationally. Modeled housing insecurity stands in the bottom 2.4% nationally, and air-toxics cancer risk settles in the bottom 2.8% nationally. Modeled utility shutoff lies in the bottom 3.3% nationally, food insecurity resides in the bottom 3.6% nationally, and humid heat lands in the bottom 4.1% nationally. Modeled transportation registers in the bottom 4.4% nationally. Against that, unemployment sits in the top 2.1% nationally, and distance to a community health center rests in the top 4.7% nationally.
To translate a couple of terms, distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Overall, the nearest healthier neighbor is ZIP 83014, 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 1.23 years of 81.6, 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.
