ST27thUS6thDefinition & 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.

The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Overall, ZIP 98023, one of several in Federal Way, Washington places in the top 13.9% healthiest ZIPs nationally (4,431st) and the top 18% of Washington (103rd).
Where the data is kindest to this area, a few readings lead the way: modeled humid heat settles in the bottom 2.7% nationally, and obesity sits in the bottom 7.0% nationally. Modeled mobility disability lies in the bottom 6.9% nationally, and coronary heart disease rests in the bottom 7.0% nationally. Modeled energy burden resides in the bottom 6.1% nationally, modeled hearing disability is in the bottom 8.1% nationally, and walkability lands in the top 9.7% nationally. Distance to a community health center stands at the national minimum, shared with about 23% of ZIPs. On the other hand, modeled expected annual loss registers in the top 5.3% nationally, and disaster risk settles in the top 6.0% nationally.
Beside the areas that surround it, park land runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. 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. Among nearby ZIPs, the nearest healthier one overall is ZIP 98070, about 2.2 miles away.

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 0.59 years of 79.7, 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.
