Median household income
$148,824
in the top 4.0% nationally
Higher is healthier
ST97thUS96thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Distance to a Superfund site
0.2 mi
in the bottom 4.3% nationally
Higher is healthier
ST5thUS4thDefinition & 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 ›Dental provider access
0.93 per 1,000 residents
in the top 7.9% nationally
Higher is healthier
ST92ndUS92ndDefinition & source ›
The number of dental offices located 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 ›Poverty rate
2.8%
in the bottom 9.1% nationally
Lower is healthier
ST12thUS9thDefinition & source ›
The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.
Full methodology ›Arsenic in groundwater
9.0%
in the top 20% nationally
Lower is healthier
ST93rdUS80thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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 ›Energy-cost burden
2.3%
in the bottom 21% nationally
Lower is healthier
ST10thUS21stDefinition & 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 ›Fine-particle (PM2.5) exceedance
0.28%
in the top 22% nationally
Lower is healthier
ST91stUS78thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Natural-disaster risk
in the top 27% nationally
Lower is healthier
ST93rdUS73rdDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›The read
From the measures that could be gathered, Chalfont, Pennsylvania (ZIP 18914) lands in the top 15% healthiest ZIPs nationally (4,960th) and the top 12.5% of Pennsylvania (217th), based on limited data; treat as directional.
The data opens carefully, on limited coverage: household income lands in the top 4.0% nationally, and dental providers stands in the top 7.9% nationally. Poverty registers in the bottom 9.1% nationally, and fiber broadband settles in the top 14.0% nationally. Home broadband subscription sits in the top 14.1% nationally. On the other hand, distance to a Superfund site lies in the bottom 4.3% nationally, and PFOA in drinking water rests in the top 15.0% nationally. Distance to a hazardous-chemical facility resides at the national minimum, shared with about 31% of ZIPs. Modeled industrial-pollution burden is in the top 16% nationally, and PFOS in drinking water lands in the top 17% nationally.
Beside the areas that surround it, park land runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Among nearby ZIPs, the nearest healthier one overall is ZIP 18901, just across the boundary.

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 0.76 years of 82.1, 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.
