Full methodology ›The read
ZIP 92335, one of several in Fontana, California, by its composite score, sits in the bottom 23% nationally (24,789th) and the bottom 18% of California (1,410th).
The measures that matter most for this area lead the way: modeled colon screening lies in the bottom 1.5% nationally, and expected annual loss rests in the top 0.5% nationally. Modeled uninsured resides in the top 3.2% nationally, and disaster risk is in the top 0.8% nationally. Crowded housing lands in the top 0.9% nationally, modeled loneliness stands in the top 3.0% nationally, and modeled housing insecurity registers in the top 3.7% nationally. Modeled fair or poor health settles in the top 5.9% nationally. On the better side, subsidized affordable housing sits in the top 2.3% nationally, and lead in tap water lies at the national minimum.
Next to the surrounding area, expected annual loss runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. For a healthier comparison close by, see ZIP 91739, 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 0.45 years of 78.2, 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
