PFOA in drinking water
100%
at the national maximum
Lower is healthier
ST99thUS99thDefinition & 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 ›Mammography
83.5%
in the top 1.8% nationally
Higher is healthier
ST44thUS98thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Transit access
6 per 1,000 residents
in the top 3.5% nationally
Higher is healthier
ST98thUS97thDefinition & source ›
The number of public-transit stops 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.
Full methodology ›PFAS in drinking water
100%
at the national maximum
Lower is healthier
ST99thUS99thDefinition & source ›
The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were 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 ›Park land
25.7%
in the top 5.5% nationally
Higher is healthier
ST96thUS95thDefinition & source ›
The share of this ZIP’s land area that is public parkland.
Full methodology ›Walkability
130 intersections/sq mi
in the top 6.5% nationally
Higher is healthier
ST83rdUS94thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Fiber broadband
97.8%
in the top 7.1% nationally
Higher is healthier
ST99thUS93rdDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Transportation noise
10.8%
in the top 7.6% nationally
Lower is healthier
ST81stUS92ndDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Fatal road crashes
2.4 per 100,000 residents per year
in the bottom 8.2% nationally
Lower is healthier
ST22ndUS8thDefinition & 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 ›Housing-cost burden

Lower is healthier
ST85thUS92ndDefinition & source ›
The share of households spending 30% or more of their income on housing.
Full methodology ›The read
ZIP 01904, one of several in Lynn, Massachusetts, by its overall standing, sits in the top 26% healthiest ZIPs nationally (8,302nd) and the bottom 26% of Massachusetts (389th).
The profile opens balanced, with readings on either hand: modeled mammography lands in the top 1.8% nationally, transit is in the top 3.5% nationally, and park land resides in the top 5.5% nationally. Walkability rests in the top 6.5% nationally, fiber broadband lies in the top 7.1% nationally, and fatal road crashes sits in the bottom 8.2% nationally. By contrast, PFOA in drinking water settles at the national maximum, and PFAS in drinking water registers at the national maximum. Modeled transportation noise stands in the top 7.6% nationally, and housing-cost burden lands in the top 8.4% nationally.
Held up against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. The nearest ZIP ranking healthier overall is ZIP 01906, 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 0.66 years of 79.4, 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. How distance is measured
