Judged by its overall standing, Danville, Washington (ZIP 99121) sits in the bottom 27% nationally (23,436th) and the bottom 8.0% of Washington (535th).
A few readings account for most of this area's strain: modeled mammography registers in the bottom 1.7% nationally, distance to a nursing home is in the top 1.6% nationally, and modeled fine-particle lies in the top 2.7% nationally. Modeled hearing disability registers in the top 3.5% nationally, distance to a community health center is in the top 3.8% nationally, and modeled coronary heart disease lies in the top 5.1% nationally. On the better side, park land registers in the top 1.3% nationally, and modeled industrial-pollution burden is in the bottom 1.3% nationally. Modeled transportation noise lies in the bottom 4.6% nationally, and housing-cost burden registers in the bottom 5.4% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. A healthier nearby ZIP overall is ZIP 99146, 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 1.93 years of 80.6, 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.
