Full methodology ›The read
On balance, and by the composite measure, ZIP 95991, one of several in Yuba City, California ranks in the bottom 24% nationally (24,354th) and the bottom 19% of California (1,389th), based on limited data; treat as directional.
The measures split the difference for this area: dental providers resides in the top 5.6% nationally, and physicians lands in the top 7.9% nationally. Against that, modeled air-toxics cancer risk registers in the top 1.1% nationally, and fine-particle sits in the top 3.4% nationally. Modeled extreme heat rests in the top 3.7% nationally, tree cover is at the national minimum, and pfas stands in the top 5.6% nationally. Modeled colon screening settles in the bottom 7.2% nationally, loneliness lies in the top 8.4% nationally, and disaster risk resides in the top 8.7% nationally.
Compared with the ZIPs it borders, park land runs far higher than the surrounding ZIPs on this measure. In plainer terms, 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. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. For a healthier nearby ZIP overall, look to ZIP 95659, 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 0.65 years of 77.3, 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
