Yucaipa, California (ZIP 92399), on the composite measure, lands in the top 38% healthiest ZIPs nationally (12,247th) and the bottom 48% of California (891st).
Where the data leans one way, another reading answers it: park land sits in the top 6.1% nationally. Distance to a nursing home registers at the national minimum, shared with about 27% of ZIPs. Subsidized affordable housing lands in the top 14.8% nationally, and lead in tap water resides in the bottom 16% nationally. On the other hand, modeled disaster risk lies in the top 0.7% nationally, and expected annual loss settles in the top 1.2% nationally. PFAS in drinking water stands at the national maximum, and PFOA in drinking water is in the top 6.1% nationally. Distance to a hazardous-chemical facility rests at the national minimum, shared with about 31% of ZIPs. Housing-cost burden sits in the top 16% nationally.
Set against the neighboring ZIPs, expected annual loss runs far higher than the surrounding ZIPs on this measure. In everyday language, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. A healthier neighbor overall sits at ZIP 92223, 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 0.39 years of 77.9, 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
