The read

By the composite health measure, Challenge, California (ZIP 95925) ranks in the bottom 7.0% nationally (29,831st) and the bottom 4.9% of California (1,636th).

A number of measures mark where this area is under strain: modeled independent living disability rests in the top 2.3% nationally, and air-toxics cancer risk stands in the top 1.3% nationally. Modeled fine-particle lies in the top 1.4% nationally, and self-care disability lands in the top 3.9% nationally. Modeled fair or poor health sits in the top 4.6% nationally, and mobility disability is in the top 3.9% nationally. On the brighter side, modeled industrial-pollution burden settles in the bottom 0.9% nationally, housing-cost burden resides at the national minimum, and poverty registers at the national minimum. Park land rests in the top 2.7% nationally.

Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. Close by, ZIP 95919, just across the boundary, ranks healthier overall.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.37 years of 77.6, and it’s very unlikely to be off by more than twice that.

Statistically similar ZIPs nationally

Similar means a ZIP whose health profile is shaped like this one’s — the same pattern of strengths and weaknesses across the nine health domains behind the Score, not similar demographics or income. The percentage is how closely the two patterns line up. A very similar ZIP can still have a different overall Score.

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
