ST91stUS95thDefinition & source ›
The share of this ZIP’s land area covered by forest.
Full methodology ›Grocery access

Higher is healthier
ST93rdUS94thDefinition & 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
From what the available data documents, St. Marys, Pennsylvania (ZIP 15857) lands in the top 44% healthiest ZIPs nationally (14,156th) and the top 41% of Pennsylvania (721st), based on limited data; treat as directional.
The profile opens on partial but real readings: modeled tree cover resides in the top 5.0% nationally. Distance to an emergency room rests at the national minimum, shared with about 11% of ZIPs. Grocery lies in the top 5.6% nationally, and fiber broadband sits in the top 7.5% nationally. Modeled extreme heat settles at the national minimum, shared with about 19% of ZIPs. Outpatient registers in the top 12.3% nationally. Distance to a nursing home stands at the national minimum, shared with about 27% of ZIPs. Mental-health providers lands in the top 13.7% nationally, and modeled humid heat is in the bottom 14.4% nationally. Against that, distance to a hazardous-chemical facility resides at the national minimum, shared with about 31% of ZIPs.
Relative to the ZIPs around it, park land runs far lower than the surrounding ZIPs on this measure. In plain 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The nearest healthier ZIP overall is ZIP 15846, just across the boundary.
What’s driving this score
Nine domains make up the ZipVitals Score — here is how this ZIP does on each, and how much each one counts.

Not placed: Chronic Disease Burden and Risk Behavior — too little of each is measured here to compare reliably. They still count toward the score (together 38% of it); we just will not publish a standing we cannot stand behind.
No data: Mental Health and Disability — not measured in this ZIP, so it is left out of the score entirely rather than estimated.

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 0.81 years of 78.5, 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.
