Full methodology ›The read
Given the gaps in coverage here, Fourmile, Kentucky (ZIP 40939) lands in the bottom 4.5% nationally (30,650th) and the bottom 38% of Kentucky (457th), based on limited data; treat as directional.
On what has been documented so far, the readings are limited but real: housing-cost burden lies at the national minimum, poverty sits at the national minimum, and homeownership settles at the national maximum. Home broadband subscription registers at the national maximum, and modeled tree cover stands in the top 7.3% nationally. Unemployment lands at the national minimum, shared with about 15% of ZIPs. Working the other way, crowded housing is in the top 0.2% nationally, and modeled mammography resides in the bottom 4.4% nationally. Modeled tooth loss rests in the top 6.3% nationally, and loud transportation noise lies in the top 6.5% nationally.
Held up against its neighbors, crowded housing runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. The nearest ZIP ranking healthier overall is ZIP 40953, about 6.7 miles away.

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 1.48 years of 73.9, 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.
