What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Pharmacy access
0.45 per 1,000 residents
in the top 6.5% nationally
Higher is healthier
ST89thUS94thDefinition & source ›
The number of pharmacies located 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 ›Tooth loss
24.4%
in the top 8.1% nationally
Lower is healthier
ST56thUS92ndDefinition & source ›
The estimated share of adults aged 65 and older who have lost all of their natural teeth.
Full methodology ›Fatal road crashes

in the top 7.7% nationally
Lower is healthier
ST91stUS92ndDefinition & 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
On the limited readings gathered so far, Mount Vernon, Kentucky (ZIP 40456) lands in the bottom 7.9% nationally (29,556th) and the bottom 50% of Kentucky (374th), based on limited data; treat as directional.
On the measures in hand, a few readings come through: distance to an emergency room lands at the national minimum, shared with about 11% of ZIPs. Pharmacy rests in the top 6.5% nationally, modeled tree cover settles in the top 9.0% nationally, and mental-health providers lands in the top 9.6% nationally. Distance to a Superfund site rests in the top 10.4% nationally. Distance to a community health center settles at the national minimum, shared with about 23% of ZIPs. Distance to a nursing home lands at the national minimum, shared with about 27% of ZIPs. Against that, modeled tooth loss rests in the top 8.1% nationally, and fatal road crashes settles in the top 7.7% nationally. Lead in tap water lands in the top 12.2% nationally.
Placed beside its immediate neighbors, park land runs far lower than the surrounding ZIPs on this measure. Put plainly, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. A healthier nearby ZIP overall is ZIP 40403, 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 0.80 years of 73.5, 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.
