A demanding profile, and several measures drive it: poverty resides at the national maximum, modeled air-toxics cancer risk sits in the top 1.6% nationally, and modeled fine-particle stands in the top 3.3% nationally. Slow internet speeds resides in the top 6.1% nationally, and walkability sits in the bottom 8.1% nationally. On the stronger side, distance to a hazardous-chemical facility stands in the top 1.4% nationally, and housing-cost burden resides at the national minimum. Homeownership sits at the national maximum, and home broadband subscription stands at the national maximum. Households without a vehicle resides at the national minimum, shared with about 16% of ZIPs.
Set within its surrounding area, poverty runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. The closest healthier ZIP overall is ZIP 95542, 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 3.27 years of 83.0, 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.
