Full methodology ›The read
Given how limited the coverage is here, Downingtown, Pennsylvania (ZIP 19335) lands in the top 4.4% healthiest ZIPs nationally (1,406th) and the top 3.6% of Pennsylvania (62nd), based on limited data; treat as directional.
From the measures that are available, a few readings can be named: household income lies in the top 4.7% nationally, and poverty lands in the bottom 8.2% nationally. Modeled mammography sits in the top 5.8% nationally, and home broadband subscription is in the top 8.6% nationally. Modeled tooth loss settles in the bottom 7.4% nationally. On the other side, modeled nitrate resides in the top 2.6% nationally, industrial-pollution burden registers in the top 3.2% nationally, and disaster risk rests in the top 6.8% nationally. Modeled pfas stands in the top 8.2% nationally, and expected annual loss lies in the top 12.4% nationally.
Set beside the nearby areas, park land runs far higher than the surrounding ZIPs on this measure. A note on the 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. For a healthier nearby comparison, ZIP 19341, just across the boundary, ranks better overall.
What’s driving this score

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 0.50 years of 80.8, 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.
