What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
PFAS in drinking water
57.3%
in the top 9.1% nationally
Lower is healthier
ST93rdUS91stDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Fatal road crashes
32.5 per 100,000 residents per year
in the top 11.3% nationally
Lower is healthier
ST94thUS89thDefinition & 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 ›Radon
2.5 pCi/L
in the top 20% nationally
Lower is healthier
ST96thUS80thDefinition & source ›
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 ›Humid extreme heat
28.6 days/year
in the bottom 26% nationally
Lower is healthier
ST95thUS26thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›The read
In its overall standing, Casco, Maine (ZIP 04015) lands in the top 47% healthiest ZIPs nationally (15,070th) and the top 41% of Maine (169th).
This area's strengths are easy to pick out across the measures: modeled extreme heat is at the national minimum, shared with about 19% of ZIPs. Modeled short sleep sits in the bottom 13.0% nationally, and obesity lands in the bottom 14.8% nationally. Crowded housing lies at the national minimum, shared with about 29% of ZIPs. Modeled tree cover stands in the top 16% nationally. Working the other way, modeled pfas rests in the top 9.1% nationally, and fatal road crashes registers in the top 11.3% nationally. Distance to a community health center resides in the top 15% nationally, and floodplain exposure settles in the top 16% nationally. Recreation is at the national minimum, shared with about 35% of ZIPs.
Put simply, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. On the overall standing, ZIP 04055, just across the boundary, ranks healthier.

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 1.23 years of 77.0, 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.
