Full methodology ›The read
Richvale, California (ZIP 95974), overall, ranks in the bottom 43% nationally (18,171st) and the bottom 32% of California (1,166th).
Several serious readings shape the profile and deserve first mention: modeled air-toxics cancer risk resides in the top 0.9% nationally, fine-particle settles in the top 1.9% nationally, and extreme heat is in the top 4.0% nationally. Modeled tree cover sits at the national minimum. On the better side, housing-cost burden lands at the national minimum, and modeled transportation noise lies at the national minimum. Homeownership stands at the national maximum, and home broadband subscription rests at the national maximum. Modeled expected annual loss registers in the bottom 2.9% nationally, and floodplain exposure resides at the national minimum.
Measured against the nearby ZIPs, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, 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. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. ZIP 95938, about 3.5 miles away, comes out 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 2.36 years of 81.2, 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.
