Full methodology ›The read
On the composite measure, Ballico, California (ZIP 95303) stands in the bottom 31% nationally (22,170th) and the bottom 24% of California (1,305th).
The weightiest signals in the profile are worth naming up front: modeled extreme heat resides in the top 1.4% nationally, and fine-particle stands in the top 1.5% nationally. Modeled nitrate sits in the top 2.1% nationally, and transportation noise resides in the top 4.1% nationally. Modeled air-toxics cancer risk stands in the top 4.5% nationally, tree cover sits at the national minimum, and colon screening resides in the bottom 5.9% nationally. Modeled disaster risk stands in the top 7.3% nationally. More positively, household income sits in the top 4.6% nationally, and home broadband subscription resides in the top 6.1% nationally.
For clarity, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. ZIP 95316, just across the boundary, ranks better overall among the ZIPs nearby.

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 1.85 years of 80.4, 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. How distance is measured
