Home broadband subscription
96.6%
in the top 12.0% nationally
Higher is healthier
ST95thUS88thDefinition & source ›
The share of households with a broadband internet subscription.
Full methodology ›PFAS in drinking water
51.8%
in the top 12.2% nationally
Lower is healthier
ST97thUS88thDefinition & 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 ›Floodplain exposure
25%
in the top 13.0% nationally
Lower is healthier
ST92ndUS87thDefinition & 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
116.2 days/year
in the top 15% nationally
Lower is healthier
ST94thUS85thDefinition & 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 ›Energy-cost burden
2.1%
in the bottom 14.5% nationally
Lower is healthier
ST9thUS14thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›PFOA in drinking water
47.1%
in the top 17% nationally
Lower is healthier
ST93rdUS83rdDefinition & 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 ›PFOS in drinking water
47.1%
in the top 18% nationally
Lower is healthier
ST91stUS82ndDefinition & source ›
The share of residents served by public water systems where PFOS, one of the most common “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 ›Tooth loss

Full methodology ›The read
On the composite measure, Harrison, Tennessee (ZIP 37341) stands in the top 36% healthiest ZIPs nationally (11,417th) and the top 9.3% of Tennessee (57th).
The strongest marks in the data are worth naming first: home broadband subscription rests in the top 12.0% nationally, and modeled arsenic lands in the bottom 12.3% nationally. Modeled energy burden settles in the bottom 14.5% nationally, and park land rests in the top 18% nationally. Modeled transportation noise lands in the bottom 18% nationally. On the other side, modeled pfas settles in the top 12.2% nationally, floodplain exposure rests in the top 13.0% nationally, and modeled humid heat lands in the top 15% nationally. PFOA in drinking water settles in the top 17% nationally, and PFOS in drinking water rests in the top 18% nationally.
Set beside the wider area around it, park land runs far higher than the surrounding ZIPs on this measure. For clarity, 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. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 37363, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.75 years of 78.1, 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.
