What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Energy-cost burden
12.9%

Lower is healthier
ST83rdUS99thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.

The number of child day-care services 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
Overall, Naknek, Alaska (ZIP 99633) lands in the bottom 36% nationally (20,654th) and the top 35% of Alaska (73rd), based on limited data; treat as directional.
A number of measures mark where this area is under strain: modeled energy burden is in the top 0.2% nationally, and distance to a nursing home settles in the top 0.2% nationally. Distance to an emergency room resides in the top 0.4% nationally, and modeled mammography registers in the bottom 2.6% nationally. Walkability rests in the bottom 3.1% nationally. On the brighter side, childcare stands in the top 0.3% nationally, modeled air-toxics cancer risk lies in the bottom 0.4% nationally, and distance to a Superfund site lands in the top 0.4% nationally. Recreation sits in the top 1.4% nationally, and modeled transportation noise is at the national minimum.
Set beside the nearby areas, households without a vehicle runs far lower than the surrounding ZIPs on this measure. A note on the terms: 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. Energy burden is the share of household income that goes to home energy bills. For a healthier nearby comparison, ZIP 99613, just across the boundary, ranks better overall.

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 3.43 years of 79.9, 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.
