Full methodology ›The read
Bainbridge Island, Washington (ZIP 98110), on the composite measure, lands in the top 3.1% healthiest ZIPs nationally (992nd) and the top 5.6% of Washington (32nd).
The profile cuts both ways, and the readings bear that out: household income stands in the top 2.2% nationally, modeled cognitive disability is in the bottom 1.4% nationally, and modeled independent living disability rests in the bottom 1.0% nationally. Modeled fair or poor health sits in the bottom 1.4% nationally, short sleep registers in the bottom 3.1% nationally, and colon screening lands in the top 2.3% nationally. Working the other way, distance to a Superfund site resides at the national minimum, and modeled disaster risk lies in the top 2.5% nationally. Modeled pfas settles in the top 3.3% nationally, and expected annual loss stands in the top 3.9% nationally.
Set against the neighboring ZIPs, park land runs far higher than the surrounding ZIPs on this measure. In everyday language, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. 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. A healthier neighbor overall sits at ZIP 98199, about 2.5 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 0.72 years of 83.9, 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. How distance is measured
