Lower is healthier
ST96thUS97thDefinition & 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 ›Lead in tap water
0 ppb

Lower is healthier
US1stDefinition & 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 ›The read
From what the available data documents, Allport, Pennsylvania (ZIP 16821) lands in the bottom 11.3% nationally (28,445th) and the bottom 6.1% of Pennsylvania (1,642nd), based on limited data; treat as directional.
On what has been documented so far, the readings are limited but real: housing-cost burden lies at the national minimum, poverty sits at the national minimum, and homeownership settles at the national maximum. Home broadband subscription registers at the national maximum, modeled disaster risk stands in the bottom 2.8% nationally, and lead in tap water lands at the national minimum. Modeled expected annual loss is in the bottom 6.4% nationally. Working the other way, modeled energy burden resides in the top 3.1% nationally, and distance to an emergency room rests in the top 6.4% nationally. Modeled short sleep lies in the top 7.0% nationally.
In plain terms, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. The nearest healthier ZIP overall is ZIP 16858, just across the boundary.

Not placed: Chronic Disease Burden and Risk Behavior — too little of each is measured here to compare reliably. They still count toward the score (together 38% of it); we just will not publish a standing we cannot stand behind.
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 1.86 years of 81.4, 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.
