Mental-health provider access
0.47 per 1,000 residents
in the top 1.0% nationally
Higher is healthier
ST98thUS99thDefinition & source ›
The number of mental-health clinics located 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 ›Walkability
0.88 intersections/sq mi
in the bottom 2.2% nationally
Higher is healthier
ST30thUS2ndDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

Higher is healthier
ST92ndUS97thDefinition & 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.

ST92ndUS90thDefinition & 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.

Chinook, Montana (ZIP 59523), in overall standing, comes out in the top 33% healthiest ZIPs nationally (10,649th) and the top 18% of Montana (61st).
A few readings each way define this mixed profile: mental-health providers is in the top 1.0% nationally, elder services lies in the top 2.6% nationally, and modeled short sleep registers in the bottom 3.1% nationally. Distance to a Superfund site is in the top 4.9% nationally, modeled air-toxics cancer risk lies in the bottom 5.0% nationally, and pharmacy registers in the top 5.8% nationally. Modeled humid heat is in the bottom 5.8% nationally. Pulling the other way, walkability lies in the bottom 2.2% nationally, and modeled radon registers in the top 9.9% nationally. Slow internet speeds is in the top 7.9% nationally.
Defined simply, for reference, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. The closest healthier ZIP overall is ZIP 59451, about 33 miles away.

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 1.54 years of 81.7, 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.
