ST95thUS99thDefinition & 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.

In its overall standing, Tombstone, Arizona (ZIP 85638) lands in the top 37% healthiest ZIPs nationally (11,732nd) and the top 39% of Arizona (154th).
This area's measures are easy to read as a mixed set: modeled loneliness settles in the bottom 2.8% nationally, pharmacy is in the top 4.5% nationally, and modeled air-toxics cancer risk sits in the bottom 5.6% nationally. Modeled binge drinking lands in the bottom 4.9% nationally, and industrial-pollution burden lies in the bottom 8.0% nationally. Set against that, fatal road crashes stands in the top 0.8% nationally, and modeled mammography rests in the bottom 3.4% nationally.

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 1.21 years of 78.1, 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
