Powells Crossroads, Tennessee (ZIP 37397), on the composite measure, lands in the bottom 10.4% nationally (28,742nd) and the bottom 25% of Tennessee (461st).
The profile cuts both ways, and the readings bear that out: fiber broadband lies in the top 2.5% nationally, modeled arsenic settles in the bottom 5.7% nationally, and modeled tree cover stands in the top 9.8% nationally. Elder services is in the top 15% nationally. Working the other way, modeled cognitive disability rests in the top 6.0% nationally, and expected annual loss sits in the top 9.5% nationally. Modeled independent living disability registers in the top 10.3% nationally, and fair or poor health lands in the top 11.8% nationally. Modeled mobility disability resides in the top 12.2% nationally, and coronary heart disease lies in the top 15% nationally.
In everyday 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. A healthier neighbor overall sits at ZIP 37327, 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 1.84 years of 72.8, 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.
