ZIP 98278, one of several in Oak Harbor, Washington, overall, ranks in the top 18% healthiest ZIPs nationally (5,840th) and the top 24% of Washington (142nd).
Taken together, the data gives a genuinely mixed reading: modeled coronary heart disease sits in the bottom 0.4% nationally, stroke lands in the bottom 0.4% nationally, and hearing disability lies in the bottom 0.6% nationally. Modeled humid heat stands in the bottom 0.7% nationally, fatal road crashes rests at the national minimum, and modeled transportation noise registers at the national minimum. On the other side, slow internet speeds resides at the national maximum, and modeled binge drinking settles in the top 1.0% nationally. Modeled mammography is in the bottom 2.3% nationally, and distance to a Superfund site sits at the national minimum.
Measured against the nearby ZIPs, slow internet speeds runs far higher than the surrounding ZIPs on this measure. Defined simply, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. ZIP 98221, about 2.4 miles away, comes out healthier 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

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.
