continue reading

This area's pressures are easy to read across the measures: modeled fine-particle stands in the top 0.2% nationally, home broadband subscription rests in the bottom 0.9% nationally, and poverty registers in the top 2.8% nationally. Modeled air-toxics cancer risk resides in the top 4.5% nationally, walkability settles in the bottom 6.2% nationally, and slow internet speeds is in the top 6.9% nationally. On the brighter side, park land sits in the top 0.4% nationally, and modeled industrial-pollution burden lands in the bottom 3.2% nationally. Distance to a hazardous-chemical facility lies in the top 4.4% nationally. Unemployment stands at the national minimum, shared with about 15% of ZIPs.

Against the wider neighborhood, park land runs far higher than the surrounding ZIPs on this measure. Put simply, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. On the overall standing, ZIP 95934, just across the boundary, ranks healthier.

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 1.68 years of 76.4, 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.
