Full methodology ›The read
Cowiche, Washington (ZIP 98923) ranks in the bottom 38% nationally (19,735th) and the bottom 18% of Washington (479th).
A number of readings press hard on the profile and set its tone: modeled fine-particle rests in the top 1.4% nationally, and arsenic lands in the top 2.4% nationally. Modeled tree cover settles at the national minimum, and colon screening rests in the bottom 7.1% nationally. Modeled uninsured lands in the top 7.1% nationally, unemployment settles in the top 8.1% nationally, and households without a vehicle rests in the top 10.0% nationally. On the brighter side, modeled short sleep lands in the bottom 8.3% nationally, and industrial-pollution burden settles in the bottom 9.9% nationally. Modeled loud transportation noise rests at the national minimum, shared with about 22% of ZIPs.
Against its neighbors, arsenic runs far higher than the surrounding ZIPs on this measure. For context, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. The closest ZIP that ranks healthier overall is ZIP 98908, 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 2.21 years of 82.1, 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.
