Full methodology ›The read
In overall standing, ZIP 98277, one of several in Oak Harbor, Washington comes out in the top 21% healthiest ZIPs nationally (6,827th) and the top 29% of Washington (167th).
The profile opens balanced, with readings on either hand: subsidized affordable housing lies in the top 2.7% nationally. Modeled extreme heat sits at the national minimum, shared with about 19% of ZIPs. Distance to a community health center settles at the national minimum, shared with about 23% of ZIPs. Modeled high cholesterol registers in the bottom 8.1% nationally, and diabetes stands in the bottom 9.4% nationally. By contrast, slow internet speeds lands in the top 1.6% nationally, and modeled pfas is in the top 3.4% nationally. Modeled disaster risk resides in the top 4.4% nationally, and distance to a Superfund site rests in the bottom 5.0% nationally. Modeled expected annual loss lies in the top 5.2% nationally.
Relative to the ZIPs around it, slow internet speeds runs far higher than the surrounding ZIPs on this measure. In plain terms, 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The nearest healthier ZIP overall is ZIP 98221, 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 0.65 years of 79.2, 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.
