Higher is healthier
ST99thUS98thDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”

The number of places for physical recreation — gyms, sports, and fitness venues — inside this ZIP’s boundary, per 1,000 residents.

Full methodology ›The read
Girdwood, Alaska (ZIP 99587), by its overall standing, sits in the top 10.1% healthiest ZIPs nationally (3,221st) and the top 1.9% of Alaska (4th), based on limited data; treat as directional.
Both sides of the picture show up plainly in this area's numbers: park land lies in the top 0.3% nationally, modeled air-toxics cancer risk sits in the bottom 0.5% nationally, and household income settles in the top 2.6% nationally. Grocery registers in the top 1.8% nationally, recreation stands in the top 2.0% nationally, and outpatient lands in the top 2.3% nationally. Distance to a hazardous-chemical facility is in the top 4.0% nationally. By contrast, walkability resides in the bottom 1.4% nationally, and distance to a nursing home rests in the top 2.9% nationally. Distance to an emergency room lies in the top 3.8% nationally.
Held up against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. Defined in plain 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 hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. The nearest ZIP ranking healthier overall is ZIP 99540, 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 3.46 years of 82.8, 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.
