Fine-particle (PM2.5) exceedance
5.0%
in the top 1.1% nationally
Lower is healthier
ST91stUS99thDefinition & 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 ›Elder-services access
0.6 per 1,000 residents
in the top 1.9% nationally
Higher is healthier
ST95thUS98thDefinition & 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 ›Distance to a hazardous-chemical facility
23.3 mi

Higher is healthier
ST86thUS97thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.
Full methodology ›Arsenic in groundwater

in the top 6.6% nationally
Lower is healthier
ST96thUS93rdDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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.

in the top 7.2% nationally
Higher is healthier
ST90thUS93rdDefinition & source ›
The number of child day-care services 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 ›The read
St. Ignatius, Montana (ZIP 59865), by its overall standing, sits in the bottom 17% nationally (26,480th) and the bottom 11.8% of Montana (301st).
The data is direct about where this area carries real strain: modeled fine-particle settles in the top 1.1% nationally, modeled arsenic registers in the top 6.6% nationally, and crowded housing stands in the top 8.4% nationally. Distance to a community health center lands in the top 10.3% nationally, modeled mammography is in the bottom 10.1% nationally, and modeled hearing disability resides in the top 10.1% nationally. More encouragingly, elder services rests in the top 1.9% nationally, and distance to a hazardous-chemical facility lies in the top 3.5% nationally. Childcare sits in the top 7.2% nationally. Modeled extreme heat settles at the national minimum, shared with about 19% of ZIPs.
Held up against its neighbors, elder services runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, 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 hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. The nearest ZIP ranking healthier overall is ZIP 59821, 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 1.09 years of 77.5, 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. How distance is measured
