Industrial-pollution burden

ST8thUS1stDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.

ST91stUS99thDefinition & source ›

ST99thUS98thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

Full methodology ›The read
By the composite health measure, Big Arm, Montana (ZIP 59910) ranks in the bottom 34% nationally (21,245th) and the bottom 28% of Montana (245th).
Several measures weigh most on this area's profile, and they come first: modeled fine-particle settles in the top 1.1% nationally, and floodplain exposure resides in the top 1.8% nationally. Unemployment registers in the top 3.1% nationally, and modeled hearing disability rests in the top 7.5% nationally. Modeled arsenic stands in the top 9.4% nationally. On the better side, modeled industrial-pollution burden lies in the bottom 0.6% nationally, modeled pfas lands in the bottom 5.2% nationally, and distance to a hazardous-chemical facility sits in the top 6.3% nationally. Households without a vehicle is at the national minimum, shared with about 16% of ZIPs. Modeled short sleep settles in the bottom 7.9% nationally.
Read against the ZIPs closest to it, floodplain exposure runs far higher than the surrounding ZIPs on this measure. To spell things out, 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. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Close by, ZIP 59860, just across the boundary, ranks healthier overall.

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 0.84 years of 80.8, 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.
