South Portland, Maine (ZIP 04106) ranks in the top 16% healthiest ZIPs nationally (5,090th) and the top 7.6% of Maine (31st).
Several signals sit on each side of the ledger here: transit is in the top 2.4% nationally, and subsidized affordable housing registers in the top 4.5% nationally. Physicians lies in the top 4.8% nationally, and outpatient is in the top 6.2% nationally. Mental-health providers registers in the top 6.7% nationally, modeled mammography lies in the top 4.4% nationally, and modeled obesity is in the bottom 9.2% nationally. Modeled extreme heat registers at the national minimum, shared with about 19% of ZIPs. Dental providers lies in the top 10.2% nationally. Working the other way, modeled disaster risk is in the top 2.9% nationally.
Against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. For context, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. The closest ZIP that ranks healthier overall is ZIP 04074, 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 0.69 years of 78.7, 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.
