What defines this ZIP

Mammography
84.6%
in the top 0.8% nationally
Higher is healthier
ST67thUS99thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Fatal road crashes
0 per 100,000 residents per year
at the national minimum
Lower is healthier
ST1stUS1stDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Lead in tap water
0 ppb
at the national minimum
Lower is healthier
US1stDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Grocery access
0.22 per 1,000 residents
in the top 6.3% nationally
Higher is healthier
ST92ndUS94thDefinition & source ›
The number of full supermarkets inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Distance to a Superfund site
1.2 mi
in the bottom 8.0% nationally
Higher is healthier
ST14thUS8thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›PFOA in drinking water
89.9%
in the top 8.7% nationally
Lower is healthier
ST80thUS91stDefinition & source ›
The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Binge drinking
19.2%
in the top 9.8% nationally
Lower is healthier
ST91stUS90thDefinition & source ›
The estimated share of adults who report binge drinking — five or more drinks on one occasion for men, four or more for women.
Full methodology ›Uninsured (under 65)
3.9%
in the bottom 2.1% nationally
Lower is healthier
ST54thUS2ndDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.

Full methodology ›The read
Blackstone, Massachusetts (ZIP 01504), in overall standing, comes out in the top 20% healthiest ZIPs nationally (6,280th) and the bottom 36% of Massachusetts (337th).
An even profile, with readings pulling both ways: modeled mammography rests in the top 0.8% nationally, fatal road crashes settles at the national minimum, and lead in tap water lands at the national minimum. Grocery rests in the top 6.3% nationally. Modeled extreme heat settles at the national minimum, shared with about 19% of ZIPs. Modeled uninsured lands in the bottom 2.1% nationally. Against that, distance to a Superfund site rests in the bottom 8.0% nationally, and PFOA in drinking water settles in the top 8.7% nationally. Modeled pfas lands in the top 10.8% nationally, and binge drinking rests in the top 9.8% nationally.
Set within its surrounding area, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, for reference, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. The closest healthier ZIP overall is ZIP 01756, 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 1.22 years of 79.3, 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.
