Full methodology ›The read
Ashburnham, Massachusetts (ZIP 01430) ranks in the top 21% healthiest ZIPs nationally (6,686th) and the bottom 34% of Massachusetts (350th).
A balanced set of signals defines this area, not any single one: modeled mammography sits in the top 1.1% nationally, and homeownership resides in the top 7.9% nationally. Modeled extreme heat stands at the national minimum, shared with about 19% of ZIPs. Modeled uninsured sits in the bottom 1.4% nationally, fatal road crashes resides in the bottom 10.9% nationally, and household income stands in the top 10.1% nationally. Modeled colon screening sits in the top 9.9% nationally, tree cover resides in the top 13.0% nationally, and humid heat stands in the bottom 13.5% nationally. By contrast, modeled radon sits in the top 13.6% nationally.
Against its neighbors, park land runs far lower than the surrounding ZIPs on this measure. For context, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The closest ZIP that ranks healthier overall is ZIP 01431, 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

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.
