The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›The read
Mariposa, California (ZIP 95338), overall, ranks in the top 50% healthiest ZIPs nationally (15,992nd) and the bottom 38% of California (1,061st).
Taken together, the data gives a genuinely mixed reading: modeled industrial-pollution burden lies in the bottom 5.4% nationally. Distance to an emergency room stands at the national minimum, shared with about 11% of ZIPs. Distance to a hazardous-chemical facility rests in the top 7.4% nationally. Distance to a community health center registers at the national minimum, shared with about 23% of ZIPs. Distance to a nursing home resides at the national minimum, shared with about 27% of ZIPs. On the other side, modeled air-toxics cancer risk settles in the top 1.7% nationally, and fine-particle is in the top 2.0% nationally. Modeled disaster risk sits in the top 2.7% nationally, housing-cost burden lands in the top 11.2% nationally, and modeled extreme heat lies in the top 17% nationally.
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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. ZIP 95306, just across the boundary, comes out healthier overall.

Highest-risk tenth
Air toxics and the years between the two ends of the risk scale
Modeled air-toxics cancer risk is 42.3 cases per million — among the tenth of compared ZIP codes with the most. Estimated life expectancy is 78.2 ± 2.0 years.
Ranked #347 of the 4,173 ZIP codes this finding names, ordered by modeled air-toxics risk, highest first.

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 1.01 years of 78.2, 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.
