Mammography
85.1%

Higher is healthier
ST76thUS99thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.

Lower is healthier
ST95thUS94thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Poverty rate

The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.

Full methodology ›The read
Charlton, Massachusetts (ZIP 01507), on the composite measure, lands in the top 19% healthiest ZIPs nationally (6,124th) and the bottom 37% of Massachusetts (332nd).
The readings split fairly evenly between strengths and concerns: modeled mammography settles in the top 0.6% nationally, and poverty stands in the bottom 8.3% nationally. Modeled extreme heat is at the national minimum, shared with about 19% of ZIPs. Modeled uninsured rests in the bottom 1.6% nationally, and household income sits in the top 10.5% nationally. Childcare registers in the top 13.1% nationally. Distance to a nursing home lands at the national minimum, shared with about 27% of ZIPs. Working the other way, modeled arsenic resides in the top 6.3% nationally. Fiber broadband lies at the national minimum, shared with about 19% of ZIPs. Outer-floodplain exposure settles in the top 13.4% nationally.
Set against the neighboring ZIPs, park land runs far lower 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". A healthier neighbor overall sits at ZIP 01566, 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 1.16 years of 80.7, 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.
