ST98thUS85thDefinition & source ›
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
By the composite health measure, ZIP 37803, one of several in Maryville, Tennessee ranks in the bottom 45% nationally (17,534th) and the top 18% of Tennessee (112th).
The signals balance out across the profile, strengths against concerns: distance to an emergency room lies in the bottom 13.3% nationally. Distance to a nursing home lands at the national minimum, shared with about 27% of ZIPs. Modeled energy burden sits in the bottom 16% nationally, and tree cover is in the top 22% nationally. Set against that, modeled expected annual loss settles in the top 11.5% nationally, radon resides in the top 14.8% nationally, and humid heat registers in the top 19% nationally. Modeled disaster risk rests in the top 20% nationally, pfas stands in the top 21% nationally, and high cholesterol lies in the top 20% nationally.
To spell things out, 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Close by, ZIP 37922, about 6.5 miles away, ranks 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 0.65 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.
