The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.

Full methodology ›Recreation access

in the top 4.0% nationally
Higher is healthier
ST98thUS96thDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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 ›Radon
3.3 pCi/L
in the top 6.7% nationally
Lower is healthier
ST96thUS93rdDefinition & 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 ›Lead in tap water
7.9 ppb
in the top 5.1% nationally
Lower is healthier
US95thDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›The read
By the composite health measure, Ketchum, Idaho (ZIP 83340) ranks in the top 4.2% healthiest ZIPs nationally (1,335th) and the top 0.4% of Idaho (1st).
The signals balance out across the profile, strengths against concerns: park land rests in the top 0.2% nationally, and modeled loneliness stands in the bottom 0.3% nationally. Modeled industrial-pollution burden lies in the bottom 1.0% nationally, and obesity lands in the bottom 1.9% nationally. Distance to a hazardous-chemical facility sits in the top 1.2% nationally, modeled humid heat is in the bottom 1.5% nationally, and modeled short sleep settles in the bottom 0.9% nationally. Recreation resides in the top 4.0% nationally. Set against that, modeled radon registers in the top 6.7% nationally, and lead in tap water rests in the top 5.1% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. This ZIP stands out as the strongest overall among its immediate neighbors.

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 1.06 years of 82.6, 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
