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.
Pharmacy access
0.51 per 1,000 residents
in the top 4.9% nationally
Higher is healthier
ST94thUS95thDefinition & source ›
The number of pharmacies located 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 ›Colon-cancer screening
72.2%
in the top 9.9% nationally
Higher is healthier
ST69thUS90thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›Radon
2.5 pCi/L
in the top 19% nationally
Lower is healthier
ST97thUS81stDefinition & 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 ›High cholesterol
35.6%
in the bottom 24% nationally
Lower is healthier
ST7thUS24thDefinition & source ›
The estimated share of adults with high cholesterol, among those who have ever been screened for it.
Full methodology ›Arsenic in groundwater
5.2%
in the top 36% nationally
Lower is healthier
ST9thUS64thDefinition & 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 ›The read
Overall, Naples, Maine (ZIP 04055) lands in the top 36% healthiest ZIPs nationally (11,544th) and the top 28% of Maine (116th).
The measures that set this area apart are worth putting up front: pharmacy registers in the top 4.9% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs. Childcare stands in the top 10.1% nationally, modeled colon screening lies in the top 9.9% nationally, and distance to a hazardous-chemical facility lands in the top 13.7% nationally. Modeled obesity sits in the bottom 15% nationally, short sleep is in the bottom 15% nationally, and tree cover settles in the top 14.9% nationally. Set against that, modeled pfas resides in the top 12.7% nationally, and distance to a nursing home registers in the top 13.2% nationally.
A note on the terms: 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. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. For a healthier nearby comparison, ZIP 04071, about 2.5 miles away, ranks better overall.

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 2.15 years of 80.9, 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.
