Fatal road crashes
65.5 per 100,000 residents per year
in the top 1.7% nationally
Lower is healthier
ST98thUS98thDefinition & 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.

45.3%

Lower is healthier
ST93rdUS96thDefinition & source ›
The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›Child-care access
0.47 per 1,000 residents
in the top 12.2% nationally
Higher is healthier
ST94thUS88thDefinition & source ›
The number of child day-care services 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 ›The read
By the composite measure, Calhoun, Tennessee (ZIP 37309) sits in the bottom 17% nationally (26,657th) and the bottom 46% of Tennessee (331st).
Where the data leans one way, another reading answers it: childcare lies in the top 12.2% nationally, modeled tree cover settles in the top 15% nationally, and modeled binge drinking stands in the bottom 16% nationally. On the other hand, fatal road crashes is in the top 1.7% nationally, modeled obesity rests in the top 4.0% nationally, and unemployment sits in the top 13.1% nationally. Modeled cognitive disability registers in the top 14.6% nationally. Distance to a hazardous-chemical facility lands at the national minimum, shared with about 31% of ZIPs. Recreation resides at the national minimum, shared with about 35% of ZIPs. Modeled high blood pressure lies in the top 17% nationally.
In plain language, 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. ZIP 37303, 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 74.3, 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.
