Full methodology ›The read
Overall, Wallula, Washington (ZIP 99363) lands in the bottom 40% nationally (19,151st) and the bottom 20% of Washington (464th), based on limited data; treat as directional.
Several measures weigh most on this area's profile, and they come first: poverty is in the top 0.5% nationally, and modeled arsenic settles in the top 4.6% nationally. Modeled pfas resides in the top 4.7% nationally, and tree cover registers at the national minimum. Modeled fine-particle rests in the top 6.9% nationally. On the better side, homeownership stands at the national maximum, and home broadband subscription lies at the national maximum. Unemployment lands at the national minimum, shared with about 15% of ZIPs. Households without a vehicle sits at the national minimum, shared with about 16% of ZIPs. Modeled short sleep is in the bottom 7.5% nationally.
Set beside the nearby areas, poverty runs far higher than the surrounding ZIPs on this measure. A note on the terms: arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. For a healthier nearby comparison, ZIP 97835, just across the boundary, ranks better overall.

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 1.92 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.
