Full methodology ›The read
Judged by its overall standing, Sonora, California (ZIP 95370) sits in the bottom 46% nationally (17,263rd) and the bottom 35% of California (1,119th).
A few readings account for most of this area's strain: modeled disaster risk lies in the top 1.6% nationally, modeled fine-particle registers in the top 2.0% nationally, and distance to an emergency room is in the top 3.3% nationally. Distance to a community health center lies in the top 5.0% nationally, modeled air-toxics cancer risk registers in the top 6.7% nationally, and housing-cost burden is in the top 7.7% nationally. On the better side, modeled industrial-pollution burden lies in the bottom 2.8% nationally, and dental providers registers in the top 4.6% nationally. Physicians is in the top 7.0% nationally, and subsidized affordable housing lies in the top 9.1% 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. A healthier nearby ZIP overall is ZIP 95222, 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 0.51 years of 79.6, 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. How distance is measured
