Full methodology ›The read
In overall standing, Idaho City, Idaho (ZIP 83631) comes out in the top 48% healthiest ZIPs nationally (15,514th) and the bottom 49% of Idaho (138th), based on limited data; treat as directional.
Both sides of the picture show up plainly in this area's numbers: distance to a hazardous-chemical facility is in the top 4.3% nationally, modeled loneliness resides in the bottom 4.5% nationally, and housing-cost burden rests in the bottom 6.2% nationally. Modeled industrial-pollution burden lies in the bottom 8.3% nationally. By contrast, modeled mammography sits in the bottom 1.2% nationally, and distance to a nursing home settles in the top 3.9% nationally. Distance to an emergency room registers in the top 6.4% nationally, and modeled fine-particle stands in the top 6.9% nationally. Slow internet speeds lands in the top 7.8% nationally, and distance to a community health center is in the top 9.2% nationally.
Relative to the ZIPs around it, park land runs far lower than the surrounding ZIPs on this measure. In plain 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. The nearest healthier ZIP overall is ZIP 83622, 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 1.96 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. How distance is measured
