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.”
Full methodology ›Coronary heart disease

The estimated share of adults who have been told by a health professional that they have coronary heart disease or angina.

Lower is healthier
ST98thUS87thDefinition & source ›
The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›The read
By the composite measure, Erwin, Tennessee (ZIP 37650) sits in the bottom 13.3% nationally (27,828th) and the bottom 35% of Tennessee (400th).
What the numbers press hardest on defines much of the story here: modeled industrial-pollution burden resides in the top 1.8% nationally, mobility disability lies in the top 9.6% nationally, and hearing disability settles in the top 9.4% nationally. Modeled coronary heart disease stands in the top 9.7% nationally, and high cholesterol is in the top 7.8% nationally. On the encouraging side, park land rests in the top 1.9% nationally, and modeled tree cover sits in the top 2.3% nationally. Fiber broadband registers in the top 3.7% nationally. Modeled extreme heat lands at the national minimum, shared with about 19% of ZIPs. Grocery resides in the top 10.2% nationally.
Compared with the ZIPs that surround it, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. In plain language, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. ZIP 28714, 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 0.70 years of 75.3, 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. How distance is measured
