Full methodology ›The read
In its overall standing, Pasco, Washington (ZIP 99301) lands in the bottom 47% nationally (16,920th) and the bottom 28% of Washington (418th), based on limited data; treat as directional.
Reading across the data, the real pressures come first: modeled nitrate settles in the top 1.4% nationally, modeled uninsured is in the top 3.9% nationally, and distance to a Superfund site sits at the national minimum. Modeled arsenic lands in the top 4.1% nationally, modeled fine-particle lies in the top 6.4% nationally, and crowded housing stands in the top 8.0% nationally. More encouragingly, subsidized affordable housing rests in the top 1.5% nationally. Distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. Modeled high cholesterol resides in the bottom 4.7% nationally, and high blood pressure settles in the bottom 5.3% nationally.
Put simply, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. On the overall standing, ZIP 99330, just across the boundary, ranks healthier.

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 0.52 years of 79.8, 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.
