Full methodology ›The read
Colchester, Connecticut (ZIP 06415), by its composite score, sits in the top 7.2% healthiest ZIPs nationally (2,287th) and the top 33% of Connecticut (91st).
The measures land in both directions, and neither dominates: modeled expected annual loss lands at the national minimum, and colon screening stands in the top 3.5% nationally. Modeled food insecurity registers in the bottom 7.8% nationally, and mental-health providers settles in the top 8.6% nationally. Modeled diabetes sits in the bottom 5.3% nationally, and household income lies in the top 8.6% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs. Subsidized affordable housing resides in the top 9.8% nationally, and modeled fair or poor health is in the bottom 7.6% nationally. Pulling the other way, modeled pfas lands in the top 10.2% nationally.
Next to the surrounding area, park land runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. For a healthier comparison close by, see ZIP 06231, 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 0.67 years of 79.3, 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
