ST87thUS94thDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams per liter.
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 ›Outer-floodplain exposure

in the top 7.4% nationally
Lower is healthier
ST84thUS93rdDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Air-toxics cancer risk
38.9 per million
in the top 7.5% nationally

The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.

ST9thUS9thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›High blood pressure

Full methodology ›The read
Judged by its overall standing, Gilroy, California (ZIP 95020) sits in the top 19% healthiest ZIPs nationally (5,954th) and the top 34% of California (584th).
A few readings each way define this mixed profile: subsidized affordable housing rests in the top 0.7% nationally, household income settles in the top 5.6% nationally, and lithium in drinking water lands in the bottom 8.7% nationally. Modeled high blood pressure rests in the bottom 6.7% nationally. Pulling the other way, modeled disaster risk settles in the top 0.5% nationally, and expected annual loss lands in the top 0.6% nationally. Modeled loneliness rests in the top 4.9% nationally, and nitrate settles in the top 5.6% nationally. Outer-floodplain exposure lands in the top 7.4% nationally, and modeled air-toxics cancer risk rests in the top 7.5% nationally.
Placed beside its immediate neighbors, expected annual loss runs far higher than the surrounding ZIPs on this measure. Put plainly, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. A healthier nearby ZIP overall is ZIP 95037, just across the boundary.

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 39.7; chronic-disease standing 93.2 (top 10%) — 54 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 0.54 years of 80.7, 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
