Civic-institution access
1.5 per 1,000 residents
in the top 2.0% nationally
Higher is healthier
ST98thUS98thDefinition & source ›
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.
Full methodology ›Fatal road crashes
0 per 100,000 residents per year
at the national minimum
Lower is healthier
ST1stUS1stDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.

Full methodology ›The read
In its overall standing, Troy, Idaho (ZIP 83871) lands in the top 21% healthiest ZIPs nationally (6,610th) and the top 9.4% of Idaho (25th), based on limited data; treat as directional.
Taken together, the data gives a genuinely mixed reading: civic is in the top 2.0% nationally, fatal road crashes sits at the national minimum, and modeled loneliness lands in the bottom 4.1% nationally. Modeled short sleep lies in the bottom 7.5% nationally, poverty stands in the bottom 9.0% nationally, and modeled pfas rests in the bottom 10.7% nationally. Childcare registers in the top 10.7% nationally, and modeled humid heat resides in the bottom 11.3% nationally. On the other side, modeled fine-particle settles in the top 2.4% nationally. Distance to a hazardous-chemical facility is at the national minimum, shared with about 31% of ZIPs.
Against the wider neighborhood, park land runs far lower than the surrounding ZIPs on this measure. Put simply, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. 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. On the overall standing, ZIP 83844, about 7.2 miles away, ranks healthier.

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 1.36 years of 79.2, 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.
