Full methodology ›The read
Given how limited the coverage is here, Grays Knob, Kentucky (ZIP 40829) lands in the bottom 4.8% nationally (30,538th) and the bottom 40% of Kentucky (445th), based on limited data; treat as directional.
From the measures that are available, a few readings can be named: modeled tree cover lies in the top 1.1% nationally, and housing-cost burden lands at the national minimum. Poverty sits at the national minimum, and home broadband subscription is at the national maximum. Distance to a hazardous-chemical facility settles in the top 2.8% nationally, and lead in tap water resides at the national minimum. On the other side, modeled tooth loss registers in the top 4.4% nationally, short sleep rests in the top 3.7% nationally, and transportation noise stands in the top 6.7% nationally. Modeled colon screening lies in the bottom 7.1% nationally.
A note on the terms: distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. For a healthier nearby comparison, ZIP 40806, about 1.9 miles away, ranks better 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 1.29 years of 72.4, 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.
