Full methodology ›The read
Conway, New Hampshire (ZIP 03818) ranks in the top 12.8% healthiest ZIPs nationally (4,103rd) and the top 35% of New Hampshire (86th).
Several signals sit on each side of the ledger here: childcare registers in the top 0.5% nationally, and mental-health providers lies in the top 0.7% nationally. Park land is in the top 0.9% nationally, and outpatient registers in the top 0.9% nationally. Dental providers lies in the top 1.2% nationally, modeled tree cover is in the top 1.9% nationally, and modeled industrial-pollution burden registers in the bottom 3.0% nationally. Physicians lies in the top 5.6% nationally. Working the other way, distance to a Superfund site is at the national minimum, and unemployment registers in the top 3.5% nationally.
Against its neighbors, childcare runs far higher than the surrounding ZIPs on this measure. For context, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. The closest ZIP that ranks healthier overall is ZIP 03259, 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 1.62 years of 82.2, 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.
