Lithium in drinking water
67 µg/L
in the top 6.9% nationally
Lower is healthier
ST89thUS93rdDefinition & 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 ›Child-care access
0.51 per 1,000 residents
in the top 10.3% nationally
Higher is healthier
ST95thUS90thDefinition & 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 ›PFAS in drinking water
13.8%
in the bottom 19% nationally
Lower is healthier
ST9thUS19thDefinition & 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 ›The read
Reagan, Tennessee (ZIP 38368), by its overall standing, sits in the bottom 17% nationally (26,640th) and the bottom 46% of Tennessee (330th).
The measures fall on both sides of the ledger for this area: childcare stands in the top 10.3% nationally. Crowded housing lands at the national minimum, shared with about 29% of ZIPs. Set against that, lithium in drinking water is in the top 6.9% nationally, and modeled high cholesterol resides in the top 10.2% nationally. Home broadband subscription rests in the bottom 14.0% nationally, and modeled cognitive disability lies in the top 15% nationally. Modeled high blood pressure sits in the top 14.6% nationally, and humid heat settles in the top 17% nationally. Modeled mobility disability registers in the top 17% nationally. Recreation stands at the national minimum, shared with about 35% of ZIPs.
Defined in plain terms, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The nearest ZIP ranking healthier overall is ZIP 38345, 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 0.78 years of 75.0, 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.
