Grassy Creek, North Carolina (ZIP 28631), in overall standing, comes out in the bottom 27% nationally (23,262nd) and the bottom 23% of North Carolina (608th).
An even profile, with readings pulling both ways: fiber broadband lands in the top 3.6% nationally, and distance to a hazardous-chemical facility rests in the top 3.8% nationally. Households without a vehicle settles at the national minimum, shared with about 16% of ZIPs. Modeled extreme heat lands at the national minimum, shared with about 19% of ZIPs. Modeled loud transportation noise rests at the national minimum, shared with about 22% of ZIPs. Against that, poverty settles in the top 1.4% nationally, and home broadband subscription lands in the bottom 7.1% nationally. Unemployment rests in the top 9.4% nationally, and modeled hearing disability settles in the top 9.4% nationally. Modeled coronary heart disease lands in the top 9.7% nationally.
Defined simply, for reference, 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. 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 closest healthier ZIP overall is ZIP 24363, 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 1.44 years of 79.1, 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.
