Full methodology ›The read
Overall, ZIP 06850, one of several in Norwalk, Connecticut lands in the top 7.6% healthiest ZIPs nationally (2,424th) and the top 35% of Connecticut (97th).
A number of measures pull each way for this area: modeled expected annual loss registers at the national minimum, and obesity rests in the bottom 6.5% nationally. Distance to an emergency room stands at the national minimum, shared with about 11% of ZIPs. Modeled high blood pressure lies in the bottom 5.8% nationally, mobility disability lands in the bottom 6.5% nationally, and hearing disability sits in the bottom 7.2% nationally. Household income is in the top 8.5% nationally. Set against that, distance to a Superfund site settles at the national minimum, modeled loud transportation noise resides in the top 7.1% nationally, and modeled pfas registers in the top 7.7% nationally.
Set beside the nearby areas, park land runs far lower than the surrounding ZIPs on this measure. A note on the terms: expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. 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. For a healthier nearby comparison, ZIP 06820, just across the boundary, ranks better overall.

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 81.8, 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.
