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.
Fatal road crashes
37.2 per 100,000 residents per year
in the top 8.3% nationally
Lower is healthier
ST90thUS92ndDefinition & 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 ›Radon
2.5 pCi/L
in the top 20% nationally
Lower is healthier
ST93rdUS80thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Humid extreme heat
100.5 days/year
in the top 23% nationally
Lower is healthier
ST94thUS77thDefinition & source ›
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
With only part of the picture in hand, Smiths Grove, Kentucky (ZIP 42171) lands in the bottom 20% nationally (25,612th) and the top 29% of Kentucky (213th), based on limited data; treat as directional.
With coverage still limited, the data points to what it can here: distance to a community health center sits at the national minimum, shared with about 23% of ZIPs. Grocery registers in the top 14.0% nationally, and modeled arsenic lands in the bottom 18% nationally. Working the other way, fatal road crashes resides in the top 8.3% nationally, and modeled short sleep lies in the top 14.0% nationally. Modeled industrial-pollution burden settles in the top 17% nationally. Recreation stands at the national minimum, shared with about 35% of ZIPs. Modeled radon is in the top 20% nationally, and humid heat rests in the top 23% nationally. Park land sits at the national minimum, shared with about 48% of ZIPs.
In plain language, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. ZIP 42159, just across the boundary, ranks healthier overall.
What’s driving this score

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 0.68 years of 75.8, 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.
