What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Grocery access
0.16 per 1,000 residents
in the top 10.2% nationally
Higher is healthier
ST91stUS90thDefinition & source ›
The number of full supermarkets inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”

The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.

Full methodology ›The read
By the composite health measure, Greenback, Tennessee (ZIP 37742) ranks in the bottom 38% nationally (19,812th) and the top 23% of Tennessee (144th).
The picture here is genuinely mixed, with readings on both sides: grocery resides in the top 10.2% nationally, and homeownership registers in the top 13.7% nationally. Housing-cost burden rests in the bottom 16% nationally, and households without a vehicle stands in the bottom 16% nationally. Modeled energy burden lies in the bottom 20% nationally. On the other side, physicians lands at the national minimum, shared with about 38% of ZIPs. Modeled humid heat sits in the top 20% nationally, pfas is in the top 20% nationally, and high cholesterol settles in the top 17% nationally. Childcare resides at the national minimum, shared with about 42% of ZIPs.
To spell things out, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Energy burden is the share of household income that goes to home energy bills. Close by, ZIP 37737, 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 0.87 years of 77.0, 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.
