Judged by its overall standing, ZIP 85297, one of several in Gilbert, Arizona sits in the top 7.4% healthiest ZIPs nationally (2,372nd) and the top 7.2% of Arizona (28th).
A balanced showing across the data, with a few readings each side: modeled coronary heart disease is in the bottom 2.7% nationally, modeled high blood pressure lies in the bottom 3.2% nationally, and lead in tap water registers at the national minimum. Modeled stroke is in the bottom 2.8% nationally. On the other hand, modeled extreme heat lies in the top 0.2% nationally, and outer-floodplain exposure registers in the top 0.2% nationally. Lithium in drinking water is in the top 0.8% nationally, and PFOA in drinking water lies at the national maximum. PFOS in drinking water registers at the national maximum, and modeled tree cover is at the national minimum.
Placed beside its immediate neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put plainly, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. A healthier nearby ZIP overall is ZIP 85295, 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 0.85 years of 79.4, 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
