Overall, Flag Pond, Tennessee (ZIP 37657) places in the bottom 14.1% nationally (27,569th) and the bottom 38% of Tennessee (383rd).
The measures that matter most for this area lead the way: modeled tooth loss lies in the top 4.2% nationally, and crowded housing rests in the top 3.0% nationally.

Modeled high cholesterol lands in the top 2.1% nationally, high blood pressure stands in the top 4.1% nationally, and industrial-pollution burden registers in the top 5.6% nationally. On the better side, modeled tree cover settles in the top 1.1% nationally, floodplain exposure sits at the national minimum, and park land lies in the top 5.5% nationally.
Beside the areas that surround it, park land runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain".

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 1.80 years of 74.8, 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.
