Distance to a Superfund site

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.

ST99thUS97thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›Transit access

in the top 4.5% nationally
Higher is healthier
ST92ndUS96thDefinition & source ›
The number of public-transit stops 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 ›Physician access

The number of physicians’ 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 ›Industrial-pollution burden
in the top 6.5% nationally
Lower is healthier
ST89thUS94thDefinition & 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 ›Lead in tap water
5.7 ppb
in the top 8.2% nationally
Lower is healthier
US92ndDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Walkability
120 intersections/sq mi
in the top 8.2% nationally
Higher is healthier
ST88thUS92ndDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Natural-disaster risk

Lower is healthier
ST99thUS91stDefinition & 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 ›Outpatient-care access
0.44 per 1,000 residents
in the top 9.8% nationally
Higher is healthier
ST90thUS90thDefinition & source ›
The number of outpatient clinics located inside this ZIP’s boundary, per 1,000 residents.

Full methodology ›The read
With coverage still partial across the sources, ZIP 18104, one of several in Allentown, Pennsylvania lands in the top 18% healthiest ZIPs nationally (5,647th) and the top 14.4% of Pennsylvania (251st), based on limited data; treat as directional.
The partial picture points to a handful of readings, with caveats: transit lands in the top 4.5% nationally, physicians lies in the top 4.7% nationally, and dental providers stands in the top 5.0% nationally. Walkability rests in the top 8.2% nationally. Modeled extreme heat registers at the national minimum, shared with about 19% of ZIPs. Set against that, distance to a Superfund site resides at the national minimum, and modeled expected annual loss settles in the top 3.4% nationally. Modeled industrial-pollution burden is in the top 6.5% nationally, and lead in tap water sits in the top 8.2% nationally. Modeled disaster risk lands in the top 8.9% nationally.
Measured against the nearby ZIPs, expected annual loss runs far higher than the surrounding ZIPs on this measure. Defined simply, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. ZIP 18069, just across the boundary, comes out healthier overall.
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 Allentown-Bethlehem-Easton, PA-NJ 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 0.54 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.
