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.

Full methodology ›The read
By the composite measure, South Naknek, Alaska (ZIP 99670) sits in the bottom 27% nationally (23,537th) and the top 38% of Alaska (81st), based on limited data; treat as directional.
Where this area is stretched, the data is unambiguous: modeled energy burden sits in the top 0.2% nationally, distance to a nursing home registers in the top 0.2% nationally, and distance to an emergency room lands in the top 0.4% nationally. Walkability resides in the bottom 0.7% nationally, unemployment lies in the top 1.3% nationally, and modeled mammography settles in the bottom 3.8% nationally. Households without a vehicle stands in the top 5.9% nationally. Better still, modeled air-toxics cancer risk is in the bottom 0.3% nationally, and distance to a Superfund site rests in the top 0.4% nationally. Modeled transportation noise sits at the national minimum.
Compared with the ZIPs that surround it, households without a vehicle runs far lower than the surrounding ZIPs on this measure. In plain language, 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. ZIP 99613, just across the boundary, ranks healthier 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.
