Full methodology ›The read
On balance, and by the composite measure, Newcastle, California (ZIP 95658) ranks in the top 19% healthiest ZIPs nationally (6,036th) and the top 34% of California (588th).
The measures split the difference for this area: modeled utility shutoff rests in the bottom 6.6% nationally, and household income is in the top 7.8% nationally. Modeled short sleep stands in the bottom 9.2% nationally, and obesity settles in the bottom 11.2% nationally. Modeled food insecurity lies in the bottom 9.8% nationally. Against that, modeled air-toxics cancer risk resides in the top 1.1% nationally, fine-particle lands in the top 2.2% nationally, and extreme heat registers in the top 6.7% nationally. Modeled pfas sits in the top 10.1% nationally, and loud transportation noise rests in the top 10.3% nationally.
Compared with the ZIPs it borders, park land runs far lower than the surrounding ZIPs on this measure. In plainer terms, 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. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. For a healthier nearby ZIP overall, look to ZIP 95650, 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 0.65 years of 80.4, 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
