Full methodology ›The read
From the measures that could be gathered, Willow Street, Pennsylvania (ZIP 17584) lands in the top 16% healthiest ZIPs nationally (5,259th) and the top 13.3% of Pennsylvania (232nd), based on limited data; treat as directional.
From the data that is available, the profile takes shape carefully: modeled arsenic lies in the bottom 12.3% nationally. Distance to a nursing home rests at the national minimum, shared with about 27% of ZIPs. Modeled colon screening resides in the top 11.0% nationally, physicians is in the top 18% nationally, and household income lands in the top 14.0% nationally. On the other side, modeled nitrate stands in the top 1.9% nationally, industrial-pollution burden registers in the top 3.5% nationally, and radon settles in the top 11.5% nationally. Homeownership sits in the bottom 13.2% nationally, and housing-cost burden lies in the top 18% nationally.
Beside the areas that surround it, industrial-pollution burden runs far lower than the surrounding ZIPs on this measure. For readers new to these terms, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Among nearby ZIPs, the nearest healthier one overall is ZIP 17606, about 6.8 miles away.
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.

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 0.83 years of 83.0, 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.
