Tooth loss

Lower is healthier
ST72ndUS96thDefinition & source ›
The estimated share of adults aged 65 and older who have lost all of their natural teeth.
Full methodology ›Lithium in drinking water
9.5 µg/L
in the bottom 2.9% nationally
Lower is healthier
ST6thUS3rdDefinition & 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 ›Tree cover
74.2%
in the top 7.3% nationally
Higher is healthier
ST66thUS93rdDefinition & source ›
The share of this ZIP’s land area covered by forest.
Full methodology ›Radon
2.9 pCi/L

Lower is healthier
ST98thUS88thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Subsidized affordable housing
114 units
in the top 17% nationally
Higher is healthier
ST91stUS83rdDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›The read
With coverage still partial across the sources, Irvine, Kentucky (ZIP 40336) lands in the bottom 3.0% nationally (31,109th) and the bottom 31% of Kentucky (512th), based on limited data; treat as directional.
This area's available measures are set out plainly: lithium in drinking water is in the bottom 2.9% nationally. Distance to an emergency room sits at the national minimum, shared with about 11% of ZIPs. Modeled tree cover lands in the top 7.3% nationally. Distance to a community health center lies at the national minimum, shared with about 23% of ZIPs. Pharmacy stands in the top 12.5% nationally, and lead in tap water rests in the bottom 16% nationally. Against that, modeled tooth loss registers in the top 4.3% nationally, and mammography resides in the bottom 10.1% nationally. Modeled radon settles in the top 12.5% nationally, and short sleep is in the top 10.9% nationally.
Measured against the nearby ZIPs, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. ZIP 40312, 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 0.56 years of 72.3, 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.
