What defines this ZIP

Fatal road crashes
1.4 per 100,000 residents per year
in the bottom 5.3% nationally
Lower is healthier
ST7thUS5thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.

Lower is healthier
ST41stUS6thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

Lower is healthier
ST28thUS6thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.

In overall standing, Steilacoom, Washington (ZIP 98388) comes out in the top 28% healthiest ZIPs nationally (9,043rd) and the top 39% of Washington (224th).
The data is generous to this ZIP in several places worth naming: fatal road crashes resides in the bottom 5.3% nationally, modeled humid heat rests in the bottom 6.2% nationally, and modeled energy burden lies in the bottom 6.3% nationally. Home broadband subscription sits in the top 9.4% nationally, transit settles in the top 11.0% nationally, and modeled tooth loss registers in the bottom 12.0% nationally. Working the other way, fiber broadband stands at the national minimum, shared with about 19% of ZIPs. Modeled transportation noise lands in the top 11.4% nationally, and disaster risk is in the top 13.6% nationally. Housing-cost burden resides in the top 15% nationally.
Relative to the ZIPs around it, park land runs far lower 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. Energy burden is the share of household income that goes to home energy bills. The nearest healthier ZIP overall is ZIP 98333, 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 1.44 years of 82.7, 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.
