Full methodology ›The read
Jamestown, California (ZIP 95327), in overall standing, comes out in the bottom 32% nationally (21,915th) and the bottom 25% of California (1,296th).
An even profile, with readings pulling both ways: modeled fine-particle rests in the top 2.5% nationally. Against that, modeled air-toxics cancer risk settles in the top 4.5% nationally, modeled disaster risk lands in the top 5.1% nationally, and housing-cost burden rests in the top 5.3% nationally. Fatal road crashes settles in the top 5.4% nationally, and unemployment lands in the top 6.3% nationally. Slow internet speeds rests in the top 7.1% nationally, and crowded housing settles in the top 8.1% nationally. Modeled extreme heat lands in the top 8.5% nationally. Fiber broadband rests at the national minimum, shared with about 19% of ZIPs.
Defined simply, for reference, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. The closest healthier ZIP overall is ZIP 95222, 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

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.
