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.

The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.

Full methodology ›The read
By the composite measure, Loudon, Tennessee (ZIP 37774) sits in the bottom 41% nationally (18,871st) and the top 20% of Tennessee (125th).
Where the data leans one way, another reading answers it: modeled binge drinking sits in the bottom 3.4% nationally, and arsenic registers in the bottom 10.6% nationally. Distance to a nursing home lands at the national minimum, shared with about 27% of ZIPs. Modeled colon screening resides in the top 11.5% nationally. On the other hand, modeled high cholesterol lies in the top 1.9% nationally, and high blood pressure settles in the top 6.3% nationally. Modeled hearing disability stands in the top 10.1% nationally, and expected annual loss is in the top 12.0% nationally. Modeled radon rests in the top 13.8% nationally, and coronary heart disease sits in the top 11.4% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. ZIP 37772, just across the boundary, 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 0.66 years of 77.5, 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.
