ST99thUS99thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.

Full methodology ›The read
On the composite measure, Mckenna, Washington (ZIP 98558) stands in the bottom 50% nationally (16,070th) and the bottom 31% of Washington (400th), based on limited data; treat as directional.
Several readings make the pressure on this area plain: unemployment sits at the national maximum, and floodplain exposure resides in the top 0.6% nationally. Modeled loud transportation noise stands in the top 3.5% nationally, and tree cover sits at the national minimum. Poverty resides in the top 5.1% nationally, distance to a nursing home stands in the top 7.4% nationally, and modeled transportation noise sits in the top 8.1% nationally. On the encouraging side, walkability resides in the top 2.5% nationally, modeled humid heat stands in the bottom 3.1% nationally, and modeled expected annual loss sits in the bottom 4.3% nationally.
Set beside the wider area around it, unemployment runs far higher than the surrounding ZIPs on this measure. For clarity, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. ZIP 98580, just across the boundary, ranks better overall among the ZIPs nearby.

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 2.25 years of 79.1, 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.
