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 without health insurance
- Food insecurity
- Adults reporting fair or poor health
- Chronic conditions
Barriers to reaching care
- Distance to the nearest emergency room
- Thin local supply of doctors
- Thin local supply of pharmacies
- Limited home internet for telehealth

Judged by its overall standing, Mammoth, Arizona (ZIP 85618) sits in the bottom 16% nationally (26,911th) and the bottom 21% of Arizona (310th).
Here the data is straightforward about what defines the area: modeled uninsured lands in the top 3.6% nationally, modeled diabetes rests in the top 2.5% nationally, and unemployment settles in the top 1.4% nationally. Modeled vision disability lands in the top 4.3% nationally, mammography rests in the bottom 3.0% nationally, and hearing disability settles in the top 3.3% nationally. Modeled arsenic lands in the top 2.7% nationally, and fair or poor health rests in the top 4.7% nationally. Better still, park land settles in the top 0.9% nationally, and outpatient lands in the top 3.2% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. A healthier nearby ZIP overall is ZIP 85132, just across the boundary. Across other measures, the ZIP 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 2.33 years of 82.3, 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
