Full methodology ›The read
By its overall health score, Hereford, Arizona (ZIP 85615) lands in the top 29% healthiest ZIPs nationally (9,201st) and the top 32% of Arizona (126th).
Strengths and concerns sit side by side across the measures here: modeled industrial-pollution burden is in the bottom 1.2% nationally, and distance to a hazardous-chemical facility stands in the top 2.5% nationally. Modeled loneliness settles in the bottom 2.8% nationally, and park land lies in the top 4.3% nationally. Modeled air-toxics cancer risk resides in the bottom 5.7% nationally. On the other hand, modeled mammography lands in the bottom 3.8% nationally, nitrate registers in the top 3.9% nationally, and disaster risk sits in the top 11.0% nationally. Modeled high cholesterol rests in the top 8.6% nationally, and unemployment is in the top 12.6% nationally.
Weighed against the ZIPs nearby, park land runs far higher than the surrounding ZIPs on this measure. To translate a couple of terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Overall, the nearest healthier neighbor is ZIP 85611, 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 1.13 years of 81.2, 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
