Full methodology ›The read
East Haddam, Connecticut (ZIP 06423), in overall standing, comes out in the top 8.9% healthiest ZIPs nationally (2,827th) and the top 41% of Connecticut (114th).
A few readings each way define this mixed profile: modeled expected annual loss settles at the national minimum, loneliness lands in the bottom 3.1% nationally, and colon screening rests in the top 3.8% nationally. Modeled food insecurity settles in the bottom 7.0% nationally, homeownership lands in the top 7.5% nationally, and modeled tree cover rests in the top 7.9% nationally. Households without a vehicle settles at the national minimum, shared with about 16% of ZIPs. Modeled fair or poor health lands in the bottom 6.0% nationally, and cognitive disability rests in the bottom 7.3% nationally. Pulling the other way, modeled pfas settles in the top 7.1% nationally.
Set within its surrounding area, park land runs far lower 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. The closest healthier ZIP overall is ZIP 06371, 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 1.67 years of 83.8, 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
