Radon
5 pCi/L
in the top 0.3% nationally
Lower is healthier
ST99thUS99thDefinition & 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 ›Mammography

Higher is healthier

The estimated share of women aged 50–74 who had a mammogram within the past two years.

The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

in the top 5.0% nationally
Lower is healthier
ST51stUS95thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest federally funded community health center, which serves patients regardless of ability to pay.
Full methodology ›Elder-services access

Higher is healthier
ST87thUS93rdDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Fiber broadband

Full methodology ›The read
Afton, Wyoming (ZIP 83110), by its composite score, sits in the top 44% healthiest ZIPs nationally (14,258th) and the top 50% of Wyoming (77th).
The data opens on a genuinely even set of readings: modeled humid heat resides in the bottom 1.1% nationally, and park land is in the top 1.7% nationally. Modeled air-toxics cancer risk lands in the bottom 2.8% nationally, and distance to a hazardous-chemical facility stands in the top 2.9% nationally. Distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. Elder services settles in the top 6.7% nationally, and fiber broadband sits in the top 7.5% nationally. On the other side, modeled radon lies in the top 0.3% nationally, modeled mammography rests in the bottom 1.5% nationally, and distance to a community health center resides in the top 5.0% nationally.
Next to the surrounding area, park land runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. 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.

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 1.08 years of 81.8, 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.
