The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.

The number of civic and social organizations inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

Full methodology ›The read
Mackay, Idaho (ZIP 83251), by its composite score, sits in the top 43% healthiest ZIPs nationally (13,862nd) and the top 46% of Idaho (122nd), based on limited data; treat as directional.
The measures fall on both sides for this area, fairly evenly: distance to a hazardous-chemical facility rests in the top 0.6% nationally, and modeled loneliness resides in the bottom 0.7% nationally. Civic is in the top 1.4% nationally, and modeled humid heat lands in the bottom 1.5% nationally. Modeled air-toxics cancer risk stands in the bottom 2.8% nationally, childcare registers in the top 2.9% nationally, and modeled industrial-pollution burden settles in the bottom 6.3% nationally. Pulling the other way, modeled hearing disability sits in the top 1.6% nationally, walkability lies in the bottom 1.6% nationally, and distance to a nursing home rests in the top 3.4% nationally.
Next to the surrounding area, civic runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, 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. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby.

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 3.31 years of 87.7, 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.
