In its overall standing, ZIP 91739, one of several in Rancho Cucamonga, California lands in the top 13.3% healthiest ZIPs nationally (4,262nd) and the top 27% of California (469th).
This area's strengths are easy to pick out across the measures: household income lies in the top 4.7% nationally, modeled hearing disability stands in the bottom 2.3% nationally, and park land rests in the top 4.1% nationally. Modeled coronary heart disease registers in the bottom 3.3% nationally, modeled stroke resides in the bottom 4.3% nationally, and home broadband subscription settles in the top 7.3% nationally. Working the other way, modeled loud transportation noise is in the top 4.0% nationally, and outer-floodplain exposure sits in the top 4.1% nationally. Modeled disaster risk lands in the top 6.9% nationally, and colon screening lies in the bottom 7.6% nationally.
Against the wider neighborhood, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put simply, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". On the overall standing, ZIP 91784, about 4.3 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 0.91 years of 82.0, 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
