By the composite health measure, ZIP 37931, one of several in Knoxville, Tennessee ranks in the top 37% healthiest ZIPs nationally (11,735th) and the top 10.0% of Tennessee (61st).
The measures that set this area apart are worth putting up front: modeled energy burden is in the bottom 11.5% nationally. Distance to a nursing home settles at the national minimum, shared with about 27% of ZIPs. Modeled stroke resides in the bottom 15.0% nationally, subsidized affordable housing registers in the top 18% nationally, and modeled coronary heart disease rests in the bottom 19% nationally. Modeled self-care disability stands in the bottom 16% nationally. Set against that, modeled air-toxics cancer risk lies in the top 6.8% nationally, and expected annual loss lands in the top 11.2% nationally. Distance to a hazardous-chemical facility sits at the national minimum, shared with about 31% of ZIPs. Modeled humid heat is in the top 18% nationally.
Read against the ZIPs closest to it, park land runs far lower than the surrounding ZIPs on this measure. To spell things out, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Close by, ZIP 37932, 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 0.59 years of 78.1, 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.
