Fiber broadband

Higher is healthier
ST98thUS98thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Child-care access

Higher is healthier
ST98thUS98thDefinition & source ›
The number of child day-care services 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.
Full methodology ›Humid extreme heat

in the bottom 13.3% nationally
Lower is healthier
ST2ndUS13thDefinition & 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 ›PFAS in drinking water

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.
Full methodology ›The read
With only some of the sources reporting, Union Dale, Pennsylvania (ZIP 18470) lands in the top 43% healthiest ZIPs nationally (13,883rd) and the top 40% of Pennsylvania (700th), based on limited data; treat as directional.
This area's available measures are set out plainly: fiber broadband resides in the top 2.4% nationally, and childcare settles in the top 2.5% nationally. Modeled extreme heat is at the national minimum, shared with about 19% of ZIPs. Modeled loud transportation noise sits at the national minimum, shared with about 22% of ZIPs. Modeled tree cover lands in the top 12.6% nationally, and humid heat lies in the bottom 13.3% nationally. Modeled disaster risk stands in the bottom 19% nationally, and physicians rests in the top 20% nationally. Against that, unemployment registers in the top 15% nationally, and modeled energy burden resides in the top 13.6% nationally.
Put simply, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. On the overall standing, ZIP 18441, just across the boundary, ranks healthier.

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 0.86 years of 79.1, 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.
