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.

Nitrate in drinking water

48.7%

in the top 0.9% nationally

Lower is healthier

ST99th
US99th
Definition & source ›

The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams per liter.

A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.

Humid extreme heat

7.3 days/year

in the bottom 4.6% nationally

Lower is healthier

ST18th
US5th
Definition & 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 ›

Loneliness

27.5%

in the bottom 5.0% nationally

Lower is healthier

ST35th
US5th
Definition & source ›

The estimated share of adults who report feeling lonely.

Distance to a Superfund site

73.5 mi

in the top 6.0% nationally

Higher is healthier

ST95th
US94th
Definition & source ›

The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.

Fine-particle (PM2.5) exceedance

1.4%

in the top 6.6% nationally

Lower is healthier

ST51st
US93rd
Definition & source ›

The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.

Full methodology ›

Air-toxics cancer risk

18.5 per million

in the bottom 6.9% nationally

Lower is healthier

ST25th
US7th
Definition & source ›

The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.

Full methodology ›

Fatal road crashes

38.8 per 100,000 residents per year

in the top 7.4% nationally

Lower is healthier

ST87th
US93rd
Definition & 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.

Lower is healthier

ST23rd
US8th
Definition & source ›

The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.

A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.

The read

By the composite measure, Warm River, Idaho (ZIP 83420) sits in the top 26% healthiest ZIPs nationally (8,316th) and the top 18% of Idaho (48th), based on limited data; treat as directional.

continue reading

The profile cuts both ways, and the readings bear that out: modeled humid heat rests in the bottom 4.6% nationally, modeled loneliness sits in the bottom 5.0% nationally, and distance to a Superfund site registers in the top 6.0% nationally. Modeled air-toxics cancer risk lands in the bottom 6.9% nationally, and pfas resides in the bottom 8.2% nationally. Modeled extreme heat lies at the national minimum, shared with about 19% of ZIPs. Working the other way, modeled nitrate settles in the top 0.9% nationally, and fine-particle stands in the top 6.6% nationally. Fatal road crashes is in the top 7.4% nationally, and modeled mammography rests in the bottom 9.4% nationally.

In plain language, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. ZIP 83414, just across the boundary, ranks healthier overall.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.86 years of 78.7, 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.
