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
3.5 pCi/L
in the top 4.8% nationally
Lower is healthier
ST96thUS95thDefinition & 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 ›Grocery access
0.18 per 1,000 residents
in the top 8.4% nationally
Higher is healthier
ST89thUS92ndDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Mental-health provider access
0.12 per 1,000 residents
in the top 8.6% nationally
Higher is healthier
ST90thUS91stDefinition & source ›
The number of mental-health clinics 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 ›Transportation noise
9.8%
in the top 8.8% nationally
Lower is healthier
ST87thUS91stDefinition & 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 ›Subsidized affordable housing
188 units
in the top 12.4% nationally
Higher is healthier
ST96thUS88thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Outer-floodplain exposure
2.4%
in the top 13.4% nationally
Lower is healthier
ST91stUS87thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Arsenic in groundwater
9.2%
in the top 19% nationally
Lower is healthier
ST93rdUS81stDefinition & 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 ›Floodplain exposure
16.2%
in the top 23% nationally
Lower is healthier
ST91stUS77thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›The read
With only some of the sources reporting, Snydertown, Pennsylvania (ZIP 17801) lands in the bottom 20% nationally (25,631st) and the bottom 11.8% of Pennsylvania (1,542nd), based on limited data; treat as directional.
This area's available measures are set out plainly: grocery sits in the top 8.4% nationally, mental-health providers lands in the top 8.6% nationally, and subsidized affordable housing lies in the top 12.4% nationally. Civic stands in the top 12.9% nationally, and pharmacy rests in the top 13.5% nationally. Distance to a nursing home registers at the national minimum, shared with about 27% of ZIPs. Against that, modeled radon resides in the top 4.8% nationally, and transportation noise settles in the top 8.8% nationally. Households without a vehicle is in the top 12.0% nationally, and outer-floodplain exposure sits in the top 13.4% nationally.
Against the wider neighborhood, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put simply, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. On the overall standing, ZIP 17821, just across the boundary, ranks healthier.
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.
Compared with the ZIP codes measured across all nine scoring domains — not with all US ZIP codes.

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 0.65 years of 76.5, 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.
