Health need and barriers to care documented here
On our reading, this ZIP code carries the overlap at its severe level: severe means at least four of the six health-need readings and at least four of the six access barriers apply to the same place.
These are two separate readings of public data that both apply to this place — never a claim that one causes the other, never a severity score, and never a statement about any person who lives here.
Health need documented here
- People without health insurance
- Food insecurity
- Housing insecurity
- Adults reporting fair or poor health
Barriers to reaching care
- Distance to the nearest emergency room
- Distance to the nearest community health center
- Households with no vehicle
- Limited home internet for telehealth

By its overall health score, Shaktoolik, Alaska (ZIP 99771) lands in the bottom 1.0% nationally (31,758th) and the bottom 17% of Alaska (176th), based on limited data; treat as directional.
Plainly stated, a few measures mark out this area: modeled energy burden lies in the top 0.3% nationally, and colon screening resides in the bottom 0.05% nationally. Modeled mammography lands in the bottom 0.4% nationally, and distance to an emergency room registers in the top 0.2% nationally. Modeled vision disability sits in the top 2.0% nationally, modeled tooth loss rests in the top 1.6% nationally, and distance to a nursing home is in the top 0.3% nationally. Better still, distance to a hazardous-chemical facility stands in the top 0.09% nationally, modeled air-toxics cancer risk settles in the bottom 0.2% nationally, and distance to a Superfund site lies in the top 0.3% nationally.
Weighed against the ZIPs nearby, distance to a hazardous-chemical facility runs far higher than the surrounding ZIPs on this measure. To translate a couple of 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. Overall, the nearest healthier neighbor is ZIP 99739, about 30 miles away.

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 2.65 years of 84.7, 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.
