Full methodology ›The read
Wahkiacus, Washington (ZIP 98670), by its overall standing, sits in the bottom 42% nationally (18,473rd) and the bottom 23% of Washington (445th).
The data is direct about where this area carries real strain: modeled mammography is in the bottom 1.7% nationally, home broadband subscription resides in the bottom 1.7% nationally, and poverty rests in the top 3.9% nationally. Distance to a nursing home lies in the top 5.5% nationally, unemployment sits in the top 5.8% nationally, and slow internet speeds settles in the top 6.8% nationally. Housing-cost burden registers in the top 7.6% nationally. More encouragingly, modeled transportation noise stands at the national minimum, and pfas lands in the bottom 3.7% nationally. Floodplain exposure is in the bottom 7.2% nationally.
Defined 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. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". The nearest ZIP ranking healthier overall is ZIP 98619, 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 1.69 years of 80.7, 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.
