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.
PFAS in drinking water
9.7%

Lower is healthier
ST2ndUS8thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.

Higher is healthier
ST81stUS91stDefinition & source ›
The share of this ZIP’s land area covered by forest.
Full methodology ›Fatal road crashes
26.8 per 100,000 residents per year
in the top 17% nationally
Lower is healthier
ST91stUS83rdDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Humid extreme heat
20.2 days/year
in the bottom 17% nationally
Lower is healthier
ST6thUS17thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Walkability
3.8 intersections/sq mi
in the bottom 23% nationally
Higher is healthier
ST5thUS23rdDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Air-toxics cancer risk
20 per million
in the bottom 25% nationally
Lower is healthier
ST1stUS25thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›The read
Given how limited the coverage is here, ZIP 16930, one of several in Liberty, Pennsylvania lands in the bottom 35% nationally (20,792nd) and the bottom 29% of Pennsylvania (1,235th), based on limited data; treat as directional.
A number of the available measures point to this much: modeled pfas registers in the bottom 8.3% nationally, and tree cover rests in the top 9.2% nationally. Modeled extreme heat stands at the national minimum, shared with about 19% of ZIPs. Modeled expected annual loss lies in the bottom 14.9% nationally, and humid heat lands in the bottom 17% nationally. On the other hand, modeled loud transportation noise sits in the top 17% nationally, fatal road crashes is in the top 17% nationally, and distance to a nursing home settles in the top 17% nationally. Recreation resides at the national minimum, shared with about 35% of ZIPs. Physicians registers at the national minimum, shared with about 38% of ZIPs.
A note on the terms: pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. For a healthier nearby comparison, ZIP 16901, just across the boundary, ranks better overall.
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 1.50 years of 80.1, 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.
