Full methodology ›The read
In overall standing, Middleton, Idaho (ZIP 83644) comes out in the top 41% healthiest ZIPs nationally (13,212th) and the top 41% of Idaho (111th).
The measures fall on both sides of the ledger for this area: modeled loneliness rests in the bottom 5.9% nationally, distance to a Superfund site lies in the top 10.0% nationally, and fatal road crashes sits in the bottom 10.8% nationally. Distance to a community health center settles at the national minimum, shared with about 23% of ZIPs. Set against that, modeled mammography registers in the bottom 1.9% nationally, and fine-particle stands in the top 4.7% nationally. Modeled air-toxics cancer risk lands in the top 8.6% nationally, and arsenic is in the top 10.7% nationally. Modeled tree cover resides in the bottom 11.2% nationally, and extreme heat rests in the top 11.5% nationally.
Relative to the ZIPs around it, park land runs far lower than the surrounding ZIPs on this measure. In plain terms, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The nearest healthier ZIP overall is ZIP 83616, 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 78.6, 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
