In overall standing, South Prairie, Washington (ZIP 98385) comes out in the top 44% healthiest ZIPs nationally (14,100th) and the bottom 38% of Washington (358th).
The measures fall on both sides of the ledger for this area: household income lies in the top 3.6% nationally, modeled humid heat sits in the bottom 3.9% nationally, and poverty settles in the bottom 6.8% nationally. Homeownership registers in the top 8.5% nationally, park land stands in the top 9.0% nationally, and home broadband subscription lands in the top 10.7% nationally. Set against that, modeled disaster risk is in the top 4.9% nationally, and crowded housing resides in the top 5.9% nationally. Outer-floodplain exposure rests in the top 8.9% nationally. Fiber broadband lies at the national minimum, shared with about 19% of ZIPs.
Relative to the ZIPs around it, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. In plain terms, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". The nearest healthier ZIP overall is ZIP 98321, 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 2.15 years of 79.6, 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.
