Arsenic in groundwater
1.0%
in the bottom 2.2% nationally
Lower is healthier
ST2ndUS2ndDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
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 ›Pharmacy access
0.58 per 1,000 residents
in the top 3.8% nationally
Higher is healthier
ST98thUS96thDefinition & source ›
The number of pharmacies 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 ›Distance to an emergency room
16.5 mi
in the top 8.9% nationally
Lower is healthier
ST98thUS91stDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Medicare-certified hospital with an emergency room.
Full methodology ›Floodplain exposure
0.37%
in the bottom 9.0% nationally
Lower is healthier
ST6thUS9thDefinition & 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 ›Distance to a hazardous-chemical facility
12.3 mi
in the top 10.8% nationally
Higher is healthier
ST94thUS89thDefinition & 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 ›The read
Big Rock, Tennessee (ZIP 37023), in overall standing, comes out in the bottom 28% nationally (23,100th) and the top 33% of Tennessee (206th).
A balanced showing across the data, with a few readings each side: modeled arsenic resides in the bottom 2.2% nationally, and pharmacy sits in the top 3.8% nationally. Unemployment stands at the national minimum, shared with about 15% of ZIPs. Floodplain exposure resides in the bottom 9.0% nationally, and distance to a hazardous-chemical facility sits in the top 10.8% nationally. Fiber broadband stands in the top 11.9% nationally. Crowded housing resides at the national minimum, shared with about 29% of ZIPs. Modeled disaster risk sits in the bottom 14.8% nationally, and tree cover stands in the top 16% nationally. On the other hand, distance to an emergency room resides in the top 8.9% nationally.
Defined simply, for reference, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. The closest healthier ZIP overall is ZIP 37079, just across the boundary.

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 1.01 years of 72.6, 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.
