The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›The read
Mystic, Connecticut (ZIP 06355), in overall standing, comes out in the top 5.4% healthiest ZIPs nationally (1,702nd) and the top 26% of Connecticut (71st).
A balanced showing across the data, with a few readings each side: modeled expected annual loss is at the national minimum, colon screening lies in the top 0.7% nationally, and food insecurity registers in the bottom 2.9% nationally. Modeled housing insecurity is in the bottom 2.9% nationally, modeled transportation lies in the bottom 3.8% nationally, and household income registers in the top 5.6% nationally. Modeled utility shutoff is in the bottom 4.4% nationally, and mammography lies in the top 3.1% nationally. On the other hand, modeled pfas registers in the top 0.6% nationally, and outer-floodplain exposure is in the top 6.1% nationally.
Set within its surrounding area, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. 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. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". The closest healthier ZIP overall is ZIP 06390, about 0.7 miles away.

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 0.91 years of 82.4, 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
