Arsenic in groundwater
25.9%
in the top 4.2% nationally
Lower is healthier
ST91stUS96thDefinition & 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 ›Lead in tap water
0 ppb
at the national minimum
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 ›Median household income
$124,213
in the top 8.4% nationally
Higher is healthier
ST81stUS92ndDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›PFAS in drinking water
57.7%
in the top 9.0% nationally
Lower is healthier
ST98thUS91stDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Outer-floodplain exposure
3.7%
in the top 9.4% nationally
Lower is healthier
ST97thUS91stDefinition & 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 ›Distance to a Superfund site
1.8 mi
in the bottom 10.0% nationally
Higher is healthier
ST21stUS10thDefinition & 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 ›Diabetes
8.9%
in the bottom 8.2% nationally
Lower is healthier
ST21stUS8thDefinition & source ›
The estimated share of adults who have been diagnosed with diabetes.
Full methodology ›Fair or poor health
14.1%
in the bottom 9.9% nationally
Lower is healthier
ST38thUS10thDefinition & source ›
The estimated share of adults who rate their own general health as fair or poor.
Full methodology ›Radon
2.5 pCi/L
in the top 20% nationally
Lower is healthier
ST91stUS80thDefinition & 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 ›Walkability
28 intersections/sq mi
in the top 28% nationally
Higher is healthier
ST90thUS72ndDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›The read
Overall, Hudson, New Hampshire (ZIP 03051) lands in the top 16% healthiest ZIPs nationally (5,028th) and the bottom 50% of New Hampshire (122nd).
A number of measures place this area on solid footing: lead in tap water sits at the national minimum, and household income is in the top 8.4% nationally. Modeled extreme heat settles at the national minimum, shared with about 19% of ZIPs. Modeled transportation resides in the bottom 11.1% nationally, diabetes registers in the bottom 8.2% nationally, and fair or poor health rests in the bottom 9.9% nationally. By contrast, modeled arsenic stands in the top 4.2% nationally, modeled pfas lies in the top 9.0% nationally, and outer-floodplain exposure lands in the top 9.4% nationally. Distance to a Superfund site sits in the bottom 10.0% nationally.
Set beside the nearby areas, park land runs far lower than the surrounding ZIPs on this measure. A note on the terms: arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. For a healthier nearby comparison, ZIP 03052, just across the boundary, ranks better overall.

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 0.60 years of 80.5, 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. How distance is measured
