On the coverage assembled to date, Crofton, Kentucky (ZIP 42217) lands in the bottom 19% nationally (26,063rd) and the top 30% of Kentucky (222nd), based on limited data; treat as directional.
The measures that are covered come first, caveats noted: modeled tree cover resides in the top 14.5% nationally, and lead in tap water lands in the bottom 15% nationally. Modeled arsenic registers in the bottom 16% nationally, and pharmacy sits in the top 17% nationally. Outer-floodplain exposure rests at the national minimum, shared with about 36% of ZIPs. By contrast, fatal road crashes is in the top 12.0% nationally, walkability stands in the bottom 12.1% nationally, and modeled tooth loss settles in the top 11.9% nationally. Home broadband subscription lies in the bottom 13.4% nationally. Recreation resides at the national minimum, shared with about 35% of ZIPs.
In plainer terms, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain".

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 1.04 years of 75.8, 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.
