This area's pressures are easy to read across the measures: modeled short sleep registers in the top 1.1% nationally, industrial-pollution burden resides in the top 2.1% nationally, and air-toxics cancer risk settles in the top 2.1% nationally. Modeled diabetes is in the top 3.7% nationally, independent living disability sits in the top 4.5% nationally, and self-care disability lands in the top 5.1% nationally. Modeled fair or poor health lies in the top 5.3% nationally, and cognitive disability stands in the top 4.6% nationally. On the brighter side, transit rests in the top 0.8% nationally, and fiber broadband registers at the national maximum.
Against the wider neighborhood, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. Put simply, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. On the overall standing, ZIP 37403, just across the boundary, ranks healthier.

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 0.74 years of 73.5, 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.
