Full methodology ›The read
Janesville, California (ZIP 96114) ranks in the bottom 43% nationally (18,393rd) and the bottom 32% of California (1,172nd).
Several readings make the pressure on this area plain: modeled fine-particle lands in the top 0.2% nationally, and disaster risk settles in the top 12.5% nationally. Modeled arsenic rests in the top 12.8% nationally. Physicians lands at the national minimum, shared with about 38% of ZIPs. On the encouraging side, modeled industrial-pollution burden settles in the bottom 1.4% nationally, distance to a Superfund site rests in the top 6.2% nationally, and park land lands in the top 8.3% nationally. Modeled humid heat settles in the bottom 12.9% nationally. Crowded housing rests at the national minimum, shared with about 29% of ZIPs. Outer-floodplain exposure lands at the national minimum, shared with about 36% of ZIPs.
Against its neighbors, park land runs far lower than the surrounding ZIPs on this measure. For context, 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 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 96137, about 13 miles away.

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 2.70 years of 83.8, 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.
