Full methodology ›The read
Humboldt, Arizona (ZIP 86329) ranks in the bottom 34% nationally (21,262nd) and the bottom 35% of Arizona (257th).
Several readings make the pressure on this area plain: modeled mammography registers in the bottom 1.4% nationally, and distance to a Superfund site lies at the national minimum. Crowded housing is in the top 7.0% nationally, and modeled pfas registers in the top 8.5% nationally. Fiber broadband lies at the national minimum, shared with about 19% of ZIPs. On the encouraging side, distance to a hazardous-chemical facility is in the top 3.3% nationally, childcare registers in the top 4.1% nationally, and park land lies in the top 7.1% nationally. Unemployment is at the national minimum, shared with about 15% of ZIPs. Modeled air-toxics cancer risk registers in the bottom 8.1% nationally.
Against its neighbors, park land runs far lower than the surrounding ZIPs on this measure. For context, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. The closest ZIP that ranks healthier overall is ZIP 86303, 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 1.88 years of 80.1, 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.
