Overall, ZIP 37409, one of several in Chattanooga, Tennessee lands in the top 50% healthiest ZIPs nationally (15,991st) and the top 16% of Tennessee (97th).
The signals balance out across the profile, strengths against concerns: transit is in the top 0.7% nationally, and pharmacy settles in the top 0.8% nationally. Park land resides in the top 1.9% nationally, and fiber broadband registers in the top 2.9% nationally. Modeled tree cover rests in the top 7.8% nationally. Distance to a community health center stands at the national minimum, shared with about 23% of ZIPs. Set against that, unemployment lies in the top 4.1% nationally, modeled air-toxics cancer risk lands in the top 7.3% nationally, and poverty sits in the top 8.1% nationally. Distance to a Superfund site is in the bottom 9.5% nationally.
Set beside the nearby areas, park land runs far higher than the surrounding ZIPs on this measure. A note on the terms: air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. For a healthier nearby comparison, ZIP 30750, just across the boundary, ranks better 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 1.68 years of 74.4, 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.
