Full methodology ›The read
By the composite health measure, Castella, California (ZIP 96017) ranks in the bottom 26% nationally (23,843rd) and the bottom 21% of California (1,364th).
On the ground, a handful of readings define this area: modeled loud transportation noise stands in the top 0.2% nationally, and fine-particle lies in the top 0.2% nationally. Modeled transportation noise lands in the top 0.8% nationally, and slow internet speeds sits in the top 2.2% nationally. Modeled high cholesterol is in the top 2.2% nationally, modeled coronary heart disease settles in the top 3.9% nationally, and distance to a nursing home resides in the top 4.2% nationally. Modeled disaster risk registers in the top 5.1% nationally. On the better side, modeled pfas rests in the bottom 1.3% nationally, and park land stands in the top 3.0% nationally.
Read against the ZIPs closest to it, loud transportation noise runs far higher than the surrounding ZIPs on this measure. To spell things out, 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Close by, ZIP 96025, just across the boundary, ranks 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 2.24 years of 78.1, 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
