Full methodology ›The read
Libby, Montana (ZIP 59923), by its composite score, sits in the bottom 21% nationally (25,409th) and the bottom 14.4% of Montana (292nd), based on limited data; treat as directional.
The measures that matter most for this area lead the way: modeled fine-particle resides in the top 1.8% nationally, and distance to a Superfund site is at the national minimum. Distance to an emergency room lands in the top 3.5% nationally, and modeled hearing disability stands in the top 5.2% nationally. Modeled radon registers in the top 11.0% nationally. On the better side, park land settles in the top 1.7% nationally, modeled industrial-pollution burden sits in the bottom 2.9% nationally, and modeled loneliness lies in the bottom 3.1% nationally. Modeled tree cover rests in the top 5.0% nationally, and distance to a hazardous-chemical facility resides in the top 5.4% nationally.
Next to the surrounding area, park land runs far lower than the surrounding ZIPs on this measure. For anyone unfamiliar, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby.

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 0.92 years of 75.2, 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.
