Powell, Tennessee (ZIP 37849), by its composite score, sits in the bottom 46% nationally (17,424th) and the top 18% of Tennessee (111th).
The measures land in both directions, and neither dominates: distance to an emergency room settles at the national minimum, shared with about 11% of ZIPs. Physicians sits in the top 13.6% nationally, and subsidized affordable housing lies in the top 13.7% nationally. Outpatient rests in the top 18% nationally, poverty resides in the bottom 19% nationally, and modeled energy burden is in the bottom 20% nationally. Dental providers lands in the top 21% nationally. Pulling the other way, modeled expected annual loss stands in the top 13.3% nationally. Distance to a hazardous-chemical facility registers at the national minimum, shared with about 31% of ZIPs. Modeled humid heat settles in the top 20% nationally.
Next to the surrounding area, park land runs far lower than the surrounding ZIPs on this measure. For anyone unfamiliar, 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. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports.

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 0.52 years of 77.6, 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.
