The measures land in both directions, and neither dominates: modeled industrial-pollution burden lies in the bottom 1.2% nationally, and tree cover rests in the top 4.1% nationally. Modeled utility shutoff resides in the bottom 5.7% nationally, and obesity is in the bottom 8.5% nationally. Civic lands in the top 7.3% nationally, and modeled food insecurity stands in the bottom 8.3% nationally. Pulling the other way, modeled fine-particle registers in the top 1.6% nationally, distance to an emergency room settles in the top 2.1% nationally, and distance to a community health center sits in the top 3.8% nationally. Housing-cost burden lies in the top 6.0% nationally.

For readers new to these terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. Among nearby ZIPs, the nearest healthier one overall is ZIP 95346, just across the boundary.

“Share” is how much of this ZIP’s score the domain accounts for. Percentages are rounded; higher is healthier in every domain. How the score works, and who it compares you with ›

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 1.29 years of 85.1, 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.
