Kittery, Maine (ZIP 03904), by its composite score, sits in the top 29% healthiest ZIPs nationally (9,231st) and the top 23% of Maine (93rd).
The measures fall on both sides for this area, fairly evenly: childcare lies in the top 6.9% nationally, and modeled food insecurity rests in the bottom 8.7% nationally. Modeled extreme heat resides at the national minimum, shared with about 19% of ZIPs. Physicians is in the top 10.5% nationally, modeled mammography lands in the top 8.7% nationally, and recreation stands in the top 12.1% nationally. Pulling the other way, slow internet speeds registers in the top 2.3% nationally, modeled arsenic settles in the top 6.0% nationally, and modeled pfas sits in the top 6.2% nationally. Households without a vehicle lies in the top 7.5% nationally.
Next to the surrounding area, slow internet speeds runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. For a healthier comparison close by, see ZIP 03801, 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 1.69 years of 84.7, 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. How distance is measured
