In its overall standing, ZIP 92337, one of several in Fontana, California lands in the top 47% healthiest ZIPs nationally (15,137th) and the bottom 41% of California (1,016th).
Reading the numbers as a whole, the picture lands somewhere in between: lead in tap water rests at the national minimum, modeled hearing disability registers in the bottom 3.6% nationally, and modeled coronary heart disease resides in the bottom 4.6% nationally. On the other side, modeled colon screening settles in the bottom 2.6% nationally, air-toxics cancer risk is in the top 2.5% nationally, and fine-particle sits in the top 4.4% nationally. Crowded housing lands in the top 4.5% nationally, and modeled loneliness lies in the top 4.5% nationally. Modeled tree cover stands at the national minimum, and distance to a Superfund site rests in the bottom 6.3% nationally.
Against the wider neighborhood, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. Put simply, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. 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. On the overall standing, ZIP 91739, about 0.7 miles away, ranks healthier.

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 0.70 years of 78.9, 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
