The estimated share of adults who usually sleep less than seven hours in a 24-hour period.

ST88thUS93rdDefinition & source ›
The number of pharmacies located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

Full methodology ›The read
Working only from the data in hand, Columbia, Kentucky (ZIP 42728) lands in the bottom 9.6% nationally (28,997th) and the top 45% of Kentucky (337th), based on limited data; treat as directional.
What little the measures show is worth setting out plainly: distance to an emergency room stands at the national minimum, shared with about 11% of ZIPs. Pharmacy settles in the top 7.2% nationally, and distance to a Superfund site lies in the top 9.5% nationally. Distance to a community health center resides at the national minimum, shared with about 23% of ZIPs. Distance to a nursing home lands at the national minimum, shared with about 27% of ZIPs. Grocery registers in the top 16% nationally, and modeled arsenic sits in the bottom 16% nationally. On the other hand, modeled short sleep rests in the top 4.9% nationally, expected annual loss is in the top 10.2% nationally, and tooth loss stands in the top 11.3% nationally.
To translate a couple of terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Overall, the nearest healthier neighbor is ZIP 42129, just across the boundary.

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 0.61 years of 75.9, 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.
