Forest Falls, California (ZIP 92339), overall, ranks in the top 30% healthiest ZIPs nationally (9,478th) and the top 45% of California (776th).
Reading the numbers as a whole, the picture lands somewhere in between: park land sits in the top 0.5% nationally, modeled humid heat lands in the bottom 1.1% nationally, and fatal road crashes lies at the national minimum. Modeled transportation noise stands in the bottom 5.4% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs. Floodplain exposure registers in the bottom 10.4% nationally. Modeled loud transportation noise resides at the national minimum, shared with about 22% of ZIPs. On the other side, housing-cost burden settles in the top 1.2% nationally, and modeled disaster risk is in the top 5.4% nationally. Walkability sits in the bottom 5.6% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined 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. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. ZIP 92305, just across the boundary, comes out 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 2.78 years of 79.5, 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
