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
- People living in poverty
- Food insecurity
- Housing insecurity
- Adults reporting fair or poor health
Barriers to reaching care
- Distance to the nearest emergency room
- Thin local supply of doctors
- Thin local supply of pharmacies
- Households with no vehicle
- Limited home internet for telehealth

Akiachak, Alaska (ZIP 99551), overall, ranks in the bottom 0.5% nationally (31,930th) and the bottom 3.8% of Alaska (203rd), based on limited data; treat as directional.
Reading the data plainly, a few things define this area first: modeled energy burden rests in the top 0.08% nationally, mammography registers in the bottom 0.02% nationally, and tooth loss resides in the top 0.3% nationally. Modeled colon screening settles in the bottom 0.3% nationally, vision disability is in the top 0.9% nationally, and independent living disability sits in the top 0.6% nationally. Modeled cognitive disability lands in the top 0.6% nationally, and transportation lies in the top 0.2% nationally. Distance to an emergency room stands in the top 0.2% nationally. More encouragingly, distance to a Superfund site rests in the top 0.3% nationally.
Defined simply, 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 99552, about 3.9 miles away, comes out healthier overall. This area also shows documented health need overlapping with barriers to reaching care, sitting in the most-affected 10% of US ZIP codes on several need measures and several access barriers.

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 1.02 years of 82.0, 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.
