Full methodology ›The read
Ninilchik, Alaska (ZIP 99639), by its overall standing, sits in the bottom 31% nationally (22,073rd) and the top 37% of Alaska (78th), based on limited data; treat as directional.
The data is direct about where this area carries real strain: modeled mammography resides in the bottom 0.5% nationally, modeled hearing disability rests in the top 2.3% nationally, and walkability lies in the bottom 2.9% nationally. Modeled coronary heart disease sits in the top 4.7% nationally, and disaster risk settles in the top 5.3% nationally. More encouragingly, elder services registers in the top 0.9% nationally, and civic stands in the top 1.3% nationally. Distance to a hazardous-chemical facility lands in the top 1.6% nationally, and modeled air-toxics cancer risk is in the bottom 2.8% nationally. Distance to a Superfund site resides in the top 4.3% nationally.
Held up against its neighbors, elder services runs far higher than the surrounding ZIPs on this measure. Defined 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The nearest ZIP ranking healthier overall is ZIP 99556, 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 2.91 years of 84.2, 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.
