Reading the numbers as a whole, the picture lands somewhere in between: lithium in drinking water registers in the bottom 4.7% nationally. On the other side, modeled air-toxics cancer risk resides in the top 4.5% nationally, industrial-pollution burden settles in the top 5.4% nationally, and expected annual loss is in the top 5.8% nationally. Modeled loneliness sits in the top 6.3% nationally, and housing insecurity lands in the top 6.9% nationally. Modeled short sleep lies in the top 7.5% nationally, and transportation stands in the top 7.3% nationally. Modeled utility shutoff rests in the top 7.8% nationally, and food insecurity registers in the top 8.0% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. ZIP 38651, just across the boundary, comes out 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 0.91 years of 75.7, 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. How distance is measured
