ST92ndUS93rdDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.

Full methodology ›The read
With only some of the sources reporting, Custer, Kentucky (ZIP 40115) lands in the bottom 1.8% nationally (31,517th) and the bottom 21% of Kentucky (585th), based on limited data; treat as directional.
This area's available measures are set out plainly: modeled disaster risk registers in the bottom 6.8% nationally, modeled pfas resides in the bottom 7.4% nationally, and fiber broadband settles in the top 9.6% nationally. Modeled loud transportation noise is at the national minimum, shared with about 22% of ZIPs. Homeownership sits in the top 11.6% nationally. Against that, modeled tooth loss lands in the top 2.1% nationally, and poverty lies in the top 6.1% nationally. Fatal road crashes stands in the top 7.1% nationally, and modeled short sleep rests in the top 7.5% nationally. Modeled mammography registers in the bottom 10.4% nationally.
Put simply, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. 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. On the overall standing, ZIP 40140, just across the boundary, ranks healthier.
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 2.75 years of 72.5, 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.
