By the composite health measure, ZIP 37221, one of several in Nashville, Tennessee ranks in the top 15% healthiest ZIPs nationally (4,886th) and the top 3.3% of Tennessee (20th).
A number of measures place this area on solid footing: modeled obesity settles in the bottom 10.7% nationally, and self-care disability resides in the bottom 5.6% nationally. Park land registers in the top 11.1% nationally. Distance to a community health center rests at the national minimum, shared with about 23% of ZIPs. Modeled energy burden stands in the bottom 9.1% nationally, modeled stroke lies in the bottom 8.3% nationally, and subsidized affordable housing lands in the top 12.2% nationally. Home broadband subscription sits in the top 12.2% nationally, and modeled coronary heart disease is in the bottom 10.9% nationally. By contrast, lead in tap water settles in the top 13.0% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. Energy burden is the share of household income that goes to home energy bills. Close by, ZIP 37027, just across the boundary, ranks healthier 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 0.58 years of 80.0, 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.
