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.
Floodplain exposure
36.8%
in the top 7.3% nationally
Lower is healthier
ST94thUS93rdDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Radon
2.5 pCi/L
in the top 20% nationally
Lower is healthier
ST95thUS80thDefinition & 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 ›The read
Sebago, Maine (ZIP 04029) ranks in the bottom 37% nationally (20,223rd) and the bottom 43% of Maine (231st).
A profile of give and take, with clear readings each way: modeled extreme heat lies at the national minimum, shared with about 19% of ZIPs. Modeled loud transportation noise is at the national minimum, shared with about 22% of ZIPs. Modeled mammography registers in the top 16% nationally. Outer-floodplain exposure lies at the national minimum, shared with about 36% of ZIPs. Modeled industrial-pollution burden is in the bottom 18% nationally, modeled obesity registers in the bottom 19% nationally, and fatal road crashes lies in the bottom 19% nationally. On the other side, floodplain exposure is in the top 7.3% nationally. Fiber broadband registers at the national minimum, shared with about 19% of ZIPs. Recreation lies at the national minimum, shared with about 35% of ZIPs.
Against its neighbors, park land runs far lower than the surrounding ZIPs on this measure. For context, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". 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 04009, 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 2.13 years of 79.9, 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.
