A balanced set of signals defines this area, not any single one: modeled obesity lands in the bottom 3.6% nationally, and park land settles in the top 5.7% nationally. Modeled utility shutoff rests in the bottom 6.6% nationally, and air-toxics cancer risk lands in the bottom 6.7% nationally. Floodplain exposure settles in the bottom 7.2% nationally, household income rests in the top 7.7% nationally, and subsidized affordable housing lands in the top 7.8% nationally. By contrast, modeled short sleep settles in the top 1.6% nationally, modeled disaster risk rests in the top 3.0% nationally, and distance to a Superfund site lands in the bottom 7.7% nationally.

Against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. For context, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The closest ZIP that ranks healthier overall is ZIP 96821, about 14 miles away.

What’s driving this score

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.53 years of 81.7, 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.
