Overall, Seldovia, Alaska (ZIP 99663) places in the bottom 24% nationally (24,277th) and the top 40% of Alaska (84th), based on limited data; treat as directional.
The measures that define this area's challenges come through directly: modeled mammography lands in the bottom 0.3% nationally, and hearing disability stands in the top 2.3% nationally. Walkability registers in the bottom 2.7% nationally, and modeled coronary heart disease settles in the top 6.0% nationally. Modeled stroke sits in the top 6.9% nationally, and distance to a nursing home lies in the top 8.7% nationally. On the stronger side, distance to a hazardous-chemical facility rests in the top 0.5% nationally, modeled air-toxics cancer risk resides in the bottom 0.5% nationally, and distance to a Superfund site is in the top 2.1% nationally. Modeled transportation noise lands at the national minimum.
Beside the areas that surround it, distance to a hazardous-chemical facility runs far higher than the surrounding ZIPs on this measure. For readers new to these 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. Among nearby ZIPs, the nearest healthier one overall is ZIP 99603, 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 2.72 years of 79.0, 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.
