Judged by its overall standing, ZIP 04103, one of several in Portland, Maine sits in the top 13.1% healthiest ZIPs nationally (4,194th) and the top 5.0% of Maine (20th).
A balanced showing across the data, with a few readings each side: subsidized affordable housing lies in the top 2.5% nationally, transit registers in the top 4.5% nationally, and mental-health providers is in the top 6.0% nationally. Modeled obesity lies in the bottom 8.7% nationally, colon screening registers in the top 5.7% nationally, and mammography is in the top 6.1% nationally. Modeled high cholesterol lies in the bottom 6.6% nationally. Modeled extreme heat registers at the national minimum, shared with about 19% of ZIPs. Modeled diabetes is in the bottom 6.1% nationally. On the other hand, modeled disaster risk lies in the top 2.2% nationally.
Placed beside its immediate neighbors, walkability runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. A healthier nearby ZIP overall is ZIP 04105, 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 0.87 years of 79.7, 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.
