Judged by its overall standing, Korbel, California (ZIP 95550) sits in the top 49% healthiest ZIPs nationally (15,704th) and the bottom 39% of California (1,041st).
A balanced showing across the data, with a few readings each side: modeled humid heat lies in the bottom 0.8% nationally, modeled transportation noise registers at the national minimum, and housing-cost burden is in the bottom 4.8% nationally. Modeled tree cover lies in the top 5.7% nationally, and home broadband subscription registers in the top 6.5% nationally. Unemployment is at the national minimum, shared with about 15% of ZIPs. On the other hand, slow internet speeds lies in the top 1.1% nationally, and modeled fine-particle registers in the top 1.7% nationally. Walkability is in the bottom 5.5% nationally, and homeownership lies in the bottom 7.1% nationally.
Placed beside its immediate neighbors, slow internet speeds runs far higher than the surrounding ZIPs on this measure. Put plainly, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. 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. A healthier nearby ZIP overall is ZIP 95525, 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 1.06 years of 81.0, 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.
