Full methodology ›The read
Hollis, New Hampshire (ZIP 03049), by its overall standing, sits in the top 5.6% healthiest ZIPs nationally (1,773rd) and the top 7.5% of New Hampshire (18th).
The measures fall on both sides of the ledger for this area: household income is in the top 2.3% nationally, modeled transportation resides in the bottom 1.9% nationally, and modeled food insecurity rests in the bottom 2.2% nationally. Modeled housing insecurity lies in the bottom 2.6% nationally, utility shutoff sits in the bottom 4.4% nationally, and mammography settles in the top 4.0% nationally. Modeled cognitive disability registers in the bottom 4.3% nationally, and poverty stands in the bottom 6.6% nationally. Set against that, modeled arsenic lands in the top 3.1% nationally, and distance to a Superfund site is in the bottom 6.2% nationally.
Held up against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined in plain 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. The nearest ZIP ranking healthier overall is ZIP 03031, just across the boundary. Looking wider, the ZIP also sits on the healthier half of the national range on at least seven of the ten good-life measures tracked here, from quiet and green space to nearby care, a combination reached by about one in twenty-five US ZIP codes.

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 0.97 years of 82.0, 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.
