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.

Lead in tap water

34 ppb

in the top 0.3% nationally

Lower is healthier

US99th
Definition & 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.

The share of this ZIP’s land area covered by forest.

Industrial-pollution burden

in the bottom 4.7% nationally

Lower is healthier

ST22nd
US5th
Definition & 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 ›

Walkability

1.6 intersections/sq mi

in the bottom 5.0% nationally

Higher is healthier

ST1st
US5th
Definition & source ›

The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

Full methodology ›

Radon

3.2 pCi/L

in the top 8.2% nationally

Lower is healthier

ST99th
US92nd
Definition & 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.

The read

On balance, and by the composite measure, Randolph, New Hampshire (ZIP 03593) ranks in the top 12.6% healthiest ZIPs nationally (4,013th) and the top 34% of New Hampshire (83rd).

continue reading

Neither strongly one way nor the other, the measures sit mixed: modeled tree cover lands in the top 0.3% nationally, and park land registers in the top 0.7% nationally. Modeled air-toxics cancer risk sits in the bottom 2.8% nationally, and housing insecurity rests in the bottom 2.9% nationally. Modeled utility shutoff is in the bottom 4.4% nationally, transportation stands in the bottom 4.4% nationally, and industrial-pollution burden settles in the bottom 4.7% nationally. Against that, lead in tap water lies in the top 0.3% nationally, walkability resides in the bottom 5.0% nationally, and modeled radon lands in the top 8.2% nationally.

Compared with the ZIPs it borders, park land runs far higher than the surrounding ZIPs on this measure. In plainer terms, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. For a healthier nearby ZIP overall, look to ZIP 03575, just across the boundary.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.81 years of 83.5, 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.
