Full methodology ›The read
From what the available data documents, Hallie, Kentucky (ZIP 41821) lands in the bottom 11.2% nationally (28,498th) and the top 42% of Kentucky (314th), based on limited data; treat as directional.
The profile opens on partial but real readings: modeled tree cover resides in the top 0.4% nationally, modeled transportation noise rests at the national minimum, and distance to a hazardous-chemical facility lies in the top 3.2% nationally. Unemployment sits at the national minimum, shared with about 15% of ZIPs. Modeled colon screening settles in the top 5.3% nationally. Modeled extreme heat registers at the national minimum, shared with about 19% of ZIPs. Modeled loud transportation noise stands at the national minimum, shared with about 22% of ZIPs. Against that, slow internet speeds lands in the top 3.4% nationally, and modeled tooth loss is in the top 6.6% nationally. Walkability resides in the bottom 8.8% nationally.
In plain 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. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. The nearest healthier ZIP overall is ZIP 41833, just across the boundary.
What’s driving this score
Nine domains make up the ZipVitals Score — here is how this ZIP does on each, and how much each one counts.

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 1.38 years of 73.5, 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.
