On balance, and by the composite measure, Newton, New Hampshire (ZIP 03858) ranks in the top 13.2% healthiest ZIPs nationally (4,205th) and the top 37% of New Hampshire (89th).
The measures split the difference for this area: household income lies in the top 5.4% nationally, and home broadband subscription resides in the top 6.4% nationally. Modeled fair or poor health lands in the bottom 7.3% nationally, and loneliness registers in the bottom 10.3% nationally. Modeled transportation sits in the bottom 11.1% nationally, mobility disability rests in the bottom 10.4% nationally, and independent living disability is in the bottom 10.2% nationally. Modeled diabetes stands in the bottom 9.4% nationally. Against that, modeled arsenic settles in the top 2.3% nationally, and distance to a Superfund site lies in the bottom 7.4% nationally.
Compared with the ZIPs it borders, park land runs far higher than the surrounding ZIPs on this measure. In plainer terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. For a healthier nearby ZIP overall, look to ZIP 03827, just across the boundary.

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 1.48 years of 80.2, 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.
