Overall, Collegedale, Tennessee (ZIP 37315) places in the top 12.6% healthiest ZIPs nationally (4,032nd) and the top 3.0% of Tennessee (18th).
The measures land in both directions, and neither dominates: modeled obesity settles in the bottom 0.8% nationally, and self-care disability sits in the bottom 0.07% nationally. Fatal road crashes lies at the national minimum, and modeled fair or poor health rests in the bottom 0.6% nationally. Modeled disaster risk resides in the bottom 5.4% nationally, vision disability is in the bottom 0.5% nationally, and expected annual loss lands in the bottom 7.9% nationally. Walkability stands in the top 8.1% nationally. Pulling the other way, modeled binge drinking registers in the top 0.8% nationally, and slow internet speeds settles in the top 1.1% nationally.
Beside the areas that surround it, slow internet speeds runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Among nearby ZIPs, the nearest healthier one overall is ZIP 37350, about 17 miles away.

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 1.81 years of 84.9, 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.
