Full methodology ›The read
In overall standing, Republic, Washington (ZIP 99166) comes out in the bottom 18% nationally (26,159th) and the bottom 3.0% of Washington (564th).
The profile opens on the burdens that define it most: modeled mammography resides in the bottom 2.4% nationally, modeled fine-particle rests in the top 1.9% nationally, and distance to a nursing home lies in the top 3.6% nationally. Unemployment sits in the top 3.6% nationally, modeled hearing disability settles in the top 6.0% nationally, and modeled coronary heart disease registers in the top 6.0% nationally. More positively, park land stands in the top 2.3% nationally, and modeled industrial-pollution burden lands in the bottom 2.4% nationally. Distance to an emergency room is at the national minimum, shared with about 11% of ZIPs. Modeled air-toxics cancer risk resides in the bottom 6.9% nationally.
Relative to the ZIPs around it, park land runs far higher than the surrounding ZIPs on this measure. 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. The nearest healthier ZIP overall is ZIP 98855, 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 1.12 years of 77.9, 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.
