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.
Grocery access
0.4 per 1,000 residents
in the top 2.4% nationally
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.”

Full methodology ›The read
On balance, and by the composite measure, Duncan, Arizona (ZIP 85534) ranks in the bottom 44% nationally (18,028th) and the bottom 43% of Arizona (223rd).
Neither strongly one way nor the other, the measures sit mixed: grocery is in the top 2.4% nationally, and distance to a Superfund site stands in the top 5.9% nationally. Modeled air-toxics cancer risk settles in the bottom 6.3% nationally. Against that, distance to a nursing home lies in the top 2.6% nationally, distance to an emergency room resides in the top 3.8% nationally, and modeled mammography lands in the bottom 5.7% nationally. Modeled nitrate registers in the top 5.5% nationally, arsenic sits in the top 7.3% nationally, and extreme heat rests in the top 8.0% nationally. Walkability is in the bottom 8.8% nationally.
Compared with the ZIPs it borders, park land runs far lower than the surrounding ZIPs on this measure. In plainer terms, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. For a healthier nearby ZIP overall, look to ZIP 85533, 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 2.53 years of 79.6, 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.
