In its overall standing, Hydesville, California (ZIP 95547) lands in the top 42% healthiest ZIPs nationally (13,518th) and the bottom 45% of California (951st).
This area's measures are easy to read as a mixed set: modeled humid heat is in the bottom 0.9% nationally, civic sits in the top 6.4% nationally, and modeled expected annual loss lands in the bottom 13.2% nationally. Homeownership lies in the top 13.8% nationally, and modeled radon stands in the bottom 11.6% nationally. Set against that, modeled fine-particle rests in the top 6.4% nationally, and unemployment registers in the top 8.3% nationally. Fiber broadband resides at the national minimum, shared with about 19% of ZIPs. Slow internet speeds settles in the top 9.9% nationally, and modeled arsenic is in the top 17% nationally.
Put simply, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. On the overall standing, ZIP 95549, about 2.9 miles away, ranks healthier.

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 1.29 years of 78.6, 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.
