Royal City, Washington (ZIP 99357), overall, ranks in the bottom 28% nationally (23,022nd) and the bottom 9.3% of Washington (527th).
Several serious readings shape the profile and deserve first mention: modeled uninsured settles in the top 0.9% nationally, colon screening is in the bottom 1.0% nationally, and mammography sits in the bottom 1.9% nationally. Modeled cognitive disability lands in the top 3.9% nationally, unemployment lies in the top 2.9% nationally, and walkability stands in the bottom 3.5% nationally. Modeled tree cover rests at the national minimum, and vision disability registers in the top 6.6% nationally. Modeled nitrate resides in the top 5.0% nationally, and fair or poor health settles in the top 7.0% nationally.
Defined simply, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. ZIP 98837, just across the boundary, comes out healthier 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 2.08 years of 86.2, 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.
