Thornton, Washington (ZIP 99176), by its overall standing, sits in the top 33% healthiest ZIPs nationally (10,710th) and the top 48% of Washington (276th), based on limited data; treat as directional.
Both sides of the picture show up plainly in this area's numbers: poverty resides at the national minimum, modeled short sleep rests in the bottom 3.1% nationally, and modeled humid heat lies in the bottom 6.5% nationally. Household income sits in the top 7.5% nationally. Unemployment settles at the national minimum, shared with about 15% of ZIPs. Modeled industrial-pollution burden registers in the bottom 7.3% nationally. Households without a vehicle stands at the national minimum, shared with about 16% of ZIPs. Modeled tooth loss lands in the bottom 3.3% nationally. By contrast, modeled fine-particle is in the top 4.0% nationally, and walkability resides in the bottom 7.2% nationally.
Defined in plain terms, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The nearest ZIP ranking healthier overall is ZIP 99111, 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 0.98 years of 80.9, 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.
