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.
Fatal road crashes
0 per 100,000 residents per year
at the national minimum
Lower is healthier
ST1stUS1stDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›High cholesterol
45.1%
in the top 4.2% nationally
Lower is healthier
ST94thUS96thDefinition & source ›
The estimated share of adults with high cholesterol, among those who have ever been screened for it.
Full methodology ›Industrial-pollution burden
in the top 8.1% nationally
Lower is healthier
ST87thUS92ndDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›PFAS in drinking water
56.5%
in the top 9.6% nationally
Lower is healthier
ST99thUS90thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Dental provider access
0.69 per 1,000 residents
in the top 14.5% nationally
Higher is healthier
ST91stUS86thDefinition & source ›
The number of dental offices located 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.
Full methodology ›Mammography
78.8%
in the top 19% nationally
Higher is healthier
ST94thUS81stDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.

ST5thUS20thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.

Full methodology ›The read
Norris, Tennessee (ZIP 37828), in overall standing, comes out in the top 49% healthiest ZIPs nationally (15,769th) and the top 16% of Tennessee (96th).
A balanced showing across the data, with a few readings each side: fatal road crashes settles at the national minimum. Unemployment lands at the national minimum, shared with about 15% of ZIPs. Modeled binge drinking rests in the bottom 10.6% nationally. Distance to a nursing home settles at the national minimum, shared with about 27% of ZIPs. Modeled tree cover lands in the top 14.4% nationally. Crowded housing rests at the national minimum, shared with about 29% of ZIPs. On the other hand, modeled high cholesterol settles in the top 4.2% nationally, and industrial-pollution burden lands in the top 8.1% nationally. Fiber broadband rests at the national minimum, shared with about 19% of ZIPs. Modeled pfas settles in the top 9.6% nationally.
Set within its surrounding area, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. The closest healthier ZIP overall is ZIP 37938, about 4.3 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 2.49 years of 82.5, 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.
