Air-toxics cancer risk
44.8 per million
in the top 1.5% nationally
Lower is healthier
ST89thUS99thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›Child-care access
1.1 per 1,000 residents
in the top 1.9% nationally
Higher is healthier
ST99thUS98thDefinition & source ›
The number of child day-care services inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Fine-particle (PM2.5) exceedance
3.0%
in the top 2.3% nationally
Lower is healthier
ST77thUS98thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Homeownership rate

at the national maximum
Higher is healthier
ST99thUS99thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.
Full methodology ›PFAS in drinking water
7.2%
in the bottom 3.7% nationally
Lower is healthier
ST5thUS4thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Walkability
1.9 intersections/sq mi
in the bottom 6.7% nationally
Higher is healthier
ST7thUS7thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Dry extreme heat

Lower is healthier
ST75thUS92ndDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›The read
Judged by its overall standing, Catheys Valley, California (ZIP 95306) sits in the top 42% healthiest ZIPs nationally (13,408th) and the bottom 45% of California (945th).
A balanced showing across the data, with a few readings each side: childcare is in the top 1.9% nationally, homeownership lies at the national maximum, and modeled pfas registers in the bottom 3.7% nationally. Unemployment is at the national minimum, shared with about 15% of ZIPs. Modeled industrial-pollution burden lies in the bottom 11.7% nationally. On the other hand, modeled air-toxics cancer risk registers in the top 1.5% nationally, and fine-particle is in the top 2.3% nationally. Walkability lies in the bottom 6.7% nationally, and modeled extreme heat registers in the top 7.9% nationally. Modeled disaster risk is in the top 13.2% nationally.
Put plainly, 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. A healthier nearby ZIP overall is ZIP 93614, about 9.7 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 1.62 years of 77.1, 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.
