What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Radon
3.3 pCi/L
in the top 6.9% nationally
Lower is healthier
ST92ndUS93rdDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Loud transportation noise
2.6%
in the top 4.7% nationally
Lower is healthier
ST95thUS95thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.
Full methodology ›Elder-services access
0.23 per 1,000 residents
in the top 6.0% nationally
Higher is healthier
ST95thUS94thDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Transportation noise
10.9%
in the top 7.4% nationally
Lower is healthier
ST89thUS93rdDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Fatal road crashes
27.2 per 100,000 residents per year
in the top 16% nationally
Lower is healthier
ST91stUS84thDefinition & 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 ›The read
From the partial coverage available here, Duncannon, Pennsylvania (ZIP 17020) lands in the bottom 41% nationally (18,826th) and the bottom 38% of Pennsylvania (1,078th), based on limited data; treat as directional.
The available readings suggest a handful of things about this area: elder services lies in the top 6.0% nationally. Distance to a nursing home is at the national minimum, shared with about 27% of ZIPs. Modeled tree cover registers in the top 16% nationally, and poverty lies in the bottom 21% nationally. By contrast, modeled radon is in the top 6.9% nationally, loud transportation noise registers in the top 4.7% nationally, and transportation noise lies in the top 7.4% nationally. Fatal road crashes is in the top 16% nationally, and outer-floodplain exposure registers in the top 19% nationally. Childcare lies at the national minimum, shared with about 42% of ZIPs.
For clarity, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. ZIP 17018, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.83 years of 76.4, 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.
