Full methodology ›The read
Groton, Massachusetts (ZIP 01450), on the composite measure, lands in the top 5.0% healthiest ZIPs nationally (1,581st) and the top 19% of Massachusetts (100th).
Where the data leans one way, another reading answers it: household income registers in the top 1.3% nationally, modeled mammography lands in the top 0.7% nationally, and modeled obesity resides in the bottom 4.4% nationally. Modeled food insecurity lies in the bottom 3.3% nationally, fatal road crashes settles in the bottom 4.4% nationally, and modeled short sleep stands in the bottom 5.5% nationally. Modeled utility shutoff is in the bottom 6.6% nationally, and home broadband subscription rests in the top 6.8% nationally. Modeled fair or poor health sits in the bottom 4.0% nationally. On the other hand, modeled arsenic registers in the top 6.7% nationally.
Set against the neighboring ZIPs, park land runs far higher than the surrounding ZIPs on this measure. In everyday language, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. A healthier neighbor overall sits at ZIP 01886, just across the boundary. Across the board, the area 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 1.61 years of 83.6, 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.
