Median household income

in the top 0.9% nationally
Higher is healthier
ST99thUS99thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Nitrate in drinking water
10.4%
in the top 3.0% nationally
Lower is healthier
ST93rdUS97thDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams per liter.
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 ›Industrial-pollution burden
in the top 4.3% nationally
Lower is healthier
ST93rdUS96thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Mammography
82.6%
in the top 2.9% nationally
Higher is healthier
ST99thUS97thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Poverty rate
1.5%
in the bottom 6.0% nationally
Lower is healthier
ST8thUS6thDefinition & source ›
The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.
Full methodology ›Fatal road crashes
1.7 per 100,000 residents per year
in the bottom 6.1% nationally
Lower is healthier
ST8thUS6thDefinition & 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 ›Home broadband subscription
98.5%
in the top 6.6% nationally
Higher is healthier
ST92ndUS93rdDefinition & source ›
The share of households with a broadband internet subscription.
Full methodology ›Distance to a Superfund site

Higher is healthier
ST11thUS9thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Energy-cost burden
1.6%
in the bottom 5.6% nationally
Lower is healthier
ST1stUS6thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Tooth loss
5.9%
in the bottom 4.4% nationally
Lower is healthier
ST3rdUS4thDefinition & source ›
The estimated share of adults aged 65 and older who have lost all of their natural teeth.
Full methodology ›The read
Working from the partial data available, Chester Springs, Pennsylvania (ZIP 19425) lands in the top 1.8% healthiest ZIPs nationally (569th) and the top 1.4% of Pennsylvania (24th), based on limited data; treat as directional.
What the available data indicates is laid out plainly: household income settles in the top 0.9% nationally, modeled mammography lands in the top 2.9% nationally, and poverty rests in the bottom 6.0% nationally. Fatal road crashes settles in the bottom 6.1% nationally, home broadband subscription lands in the top 6.6% nationally, and modeled energy burden rests in the bottom 5.6% nationally. Modeled tooth loss settles in the bottom 4.4% nationally. Set against that, modeled nitrate lands in the top 3.0% nationally, and industrial-pollution burden rests in the top 4.3% nationally. Distance to a Superfund site settles in the bottom 8.6% nationally.
Set within its surrounding area, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, for reference, 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The closest healthier ZIP overall is ZIP 19341, 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. Compare it against the US, this state and the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD metro area.

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 0.97 years of 82.5, 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.
