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.
Elder-services access
0.78 per 1,000 residents
in the top 1.2% nationally
Higher is healthier
ST99thUS99thDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Fatal road crashes
64.1 per 100,000 residents per year
in the top 1.9% nationally
Lower is healthier
ST97thUS98thDefinition & 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 ›Lithium in drinking water
90 µg/L
in the top 3.1% nationally
Lower is healthier
ST93rdUS97thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
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 ›Transportation noise
0.05%
in the bottom 7.2% nationally
Lower is healthier
ST4thUS7thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Distance to a hazardous-chemical facility
12.2 mi
in the top 10.9% nationally
Higher is healthier
ST93rdUS89thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.
Full methodology ›High cholesterol
43.7%
in the top 7.8% nationally
Lower is healthier
ST86thUS92ndDefinition & source ›
The estimated share of adults with high cholesterol, among those who have ever been screened for it.
Full methodology ›Floodplain exposure
26.2%
in the top 12.2% nationally
Lower is healthier
ST93rdUS88thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Humid extreme heat
115.5 days/year
in the top 15% nationally
Lower is healthier
ST92ndUS85thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Median household income
$45,714
in the bottom 9.7% nationally
Higher is healthier
ST13thUS10thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Distance to a nursing home

The distance in miles from this ZIP’s edge to the nearest Medicare- or Medicaid-certified nursing home.
Full methodology ›The read
Sardis, Tennessee (ZIP 38371), by its composite score, sits in the bottom 14.3% nationally (27,497th) and the bottom 38% of Tennessee (382nd).
The measures that matter most for this area lead the way: fatal road crashes sits in the top 1.9% nationally, and lithium in drinking water lies in the top 3.1% nationally. Modeled high cholesterol rests in the top 7.8% nationally, and floodplain exposure resides in the top 12.2% nationally. Modeled mammography is in the bottom 12.4% nationally, and coronary heart disease lands in the top 12.3% nationally. On the better side, elder services stands in the top 1.2% nationally, modeled transportation noise registers in the bottom 7.2% nationally, and distance to a hazardous-chemical facility settles in the top 10.9% nationally. Modeled loud transportation noise sits at the national minimum, shared with about 22% of ZIPs.
Next to the surrounding area, elder services runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels.

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 0.83 years of 74.5, 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.
