Full methodology ›The read
By the composite measure, ZIP 95355, one of several in Modesto, California sits in the top 49% healthiest ZIPs nationally (15,763rd) and the bottom 39% of California (1,045th).
Where the data leans one way, another reading answers it: distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. Walkability lands in the top 6.0% nationally. On the other hand, modeled fine-particle resides in the top 1.6% nationally, and lead in tap water lies in the top 1.6% nationally. PFOA in drinking water settles at the national maximum, and PFOS in drinking water stands at the national maximum. Modeled extreme heat is in the top 2.2% nationally, and air-toxics cancer risk rests in the top 4.5% nationally. Modeled tree cover sits at the national minimum, and PFAS in drinking water registers at the national maximum.
Compared with the ZIPs that surround it, walkability runs far higher than the surrounding ZIPs on this measure. In plain language, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 95356, just across the boundary, ranks healthier overall.

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 0.51 years of 77.4, 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
