Full methodology ›The read
Judged by its overall standing, Samoa, California (ZIP 95564) sits in the top 45% healthiest ZIPs nationally (14,443rd) and the bottom 43% of California (982nd).
A few readings each way define this mixed profile: modeled humid heat stands in the bottom 0.5% nationally, transportation noise resides in the bottom 4.8% nationally, and high cholesterol sits in the bottom 4.5% nationally. Modeled air-toxics cancer risk stands in the bottom 6.2% nationally, and high blood pressure resides in the bottom 5.0% nationally. Households without a vehicle sits at the national minimum, shared with about 16% of ZIPs. Pulling the other way, modeled disaster risk stands in the top 3.2% nationally, and binge drinking resides in the top 4.2% nationally. Floodplain exposure sits in the top 4.7% nationally, and modeled pfas stands in the top 7.1% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. 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. A healthier nearby ZIP overall is ZIP 95524, about 3.4 miles away.

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 1.67 years of 78.8, 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
