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
On the composite measure, Chattaroy, Washington (ZIP 99003) stands in the top 38% healthiest ZIPs nationally (12,312th) and the bottom 46% of Washington (316th).
The bright spots in the data define much of the story here: modeled humid heat stands in the bottom 12.9% nationally, and floodplain exposure sits in the bottom 18% nationally. Childcare resides in the top 18% nationally, and modeled tooth loss stands in the bottom 17% nationally. On the other side, distance to a Superfund site sits in the bottom 3.7% nationally, and modeled fine-particle resides in the top 4.0% nationally. Fiber broadband stands at the national minimum, shared with about 19% of ZIPs. PFOS in drinking water sits in the top 16% nationally, and distance to a nursing home resides in the top 16% nationally. Recreation stands at the national minimum, shared with about 35% of ZIPs.
Set beside the wider area around it, park land runs far lower than the surrounding ZIPs on this measure. For clarity, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 99005, just across the boundary, ranks better overall among the ZIPs nearby.

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 1.75 years of 77.7, 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.
