On balance, and by the composite measure, Clark Fork, Idaho (ZIP 83811) ranks in the bottom 40% nationally (19,102nd) and the bottom 32% of Idaho (183rd).
The measures that press hardest set the tone here: crowded housing is in the top 1.2% nationally, and modeled fine-particle stands in the top 1.9% nationally. Modeled hearing disability settles in the top 2.8% nationally, and mammography lies in the bottom 6.5% nationally. Unemployment resides in the top 6.2% nationally. On the stronger side, modeled loneliness lands in the bottom 1.2% nationally, distance to a hazardous-chemical facility registers in the top 1.5% nationally, and modeled industrial-pollution burden sits in the bottom 1.8% nationally. Park land rests in the top 2.6% nationally, and modeled short sleep is in the bottom 5.8% nationally.
Compared with the ZIPs it borders, crowded housing runs far higher than the surrounding ZIPs on this measure. In plainer terms, 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. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. For a healthier nearby ZIP overall, look to ZIP 83803, just across the boundary.

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 2.20 years of 76.6, 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.
