Full methodology ›The read
Overall, Hanford, California (ZIP 93230) lands in the bottom 28% nationally (23,147th) and the bottom 22% of California (1,343rd).
Where the load on this area runs deepest, the data leads: modeled fine-particle rests in the top 0.2% nationally, and extreme heat stands in the top 0.8% nationally. Modeled disaster risk lies in the top 1.7% nationally, and arsenic lands in the top 3.0% nationally. Modeled air-toxics cancer risk sits in the top 6.3% nationally, modeled loneliness is in the top 7.5% nationally, and crowded housing settles in the top 7.5% nationally. Modeled nitrate resides in the top 7.9% nationally, and colon screening registers in the bottom 7.9% nationally. More encouragingly, subsidized affordable housing rests in the top 4.0% nationally.
A note on the terms: fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. For a healthier nearby comparison, ZIP 93245, just across the boundary, ranks better overall.

Findings that name this ZIP
2 of our published findings list this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.
Heavy environment, light chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 3.0 (bottom 10%); chronic-disease standing 79.6 — 77 points apart, heavier on the environment than it is on chronic illness.

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 0.48 years of 78.8, 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. How distance is measured
