Health need and barriers to care documented here
On our reading, this ZIP code carries the overlap at its severe level: severe means at least four of the six health-need readings and at least four of the six access barriers apply to the same place.
These are two separate readings of public data that both apply to this place — never a claim that one causes the other, never a severity score, and never a statement about any person who lives here.
Health need documented here
- People living in poverty
- Food insecurity
- Adults reporting fair or poor health
- Chronic conditions
Barriers to reaching care
- Distance to the nearest community health center
- Thin local supply of doctors
- Thin local supply of pharmacies
- Limited home internet for telehealth

By the composite health measure, Dixon, Montana (ZIP 59831) ranks in the bottom 3.3% nationally (31,039th) and the bottom 3.6% of Montana (329th).
A number of measures mark what daily life looks like here: modeled fine-particle resides in the top 0.7% nationally, and arsenic registers in the top 2.0% nationally. Modeled mammography rests in the bottom 3.1% nationally, and hearing disability stands in the top 3.0% nationally. Modeled independent living disability lies in the top 4.5% nationally, vision disability lands in the top 6.0% nationally, and self-care disability sits in the top 5.9% nationally. Modeled colon screening is in the bottom 5.8% nationally, walkability settles in the bottom 5.1% nationally, and modeled tooth loss resides in the top 6.7% nationally.
Read against the ZIPs closest to it, park land runs far lower than the surrounding ZIPs on this measure. To spell things out, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Close by, ZIP 59821, just across the boundary, ranks healthier overall. On other measures, the area also shows documented health need overlapping with barriers to reaching care, sitting in the most-affected 10% of US ZIP codes on several need measures and several access barriers.

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 1.60 years of 78.0, 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
