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.

The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
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 ›The read
Keyes, California (ZIP 95328), in overall standing, comes out in the bottom 13.2% nationally (27,849th) and the bottom 10.1% of California (1,547th).
A few readings account for most of this area's strain: modeled nitrate lies in the top 0.5% nationally, colon screening registers in the bottom 2.5% nationally, and uninsured is in the top 3.7% nationally. Crowded housing lies in the top 1.7% nationally, modeled extreme heat registers in the top 1.7% nationally, and modeled fine-particle is in the top 2.3% nationally. Housing-cost burden lies in the top 2.4% nationally, and modeled fair or poor health registers in the top 5.9% nationally. Modeled housing insecurity is in the top 4.2% nationally. On the better side, floodplain exposure lies at the national minimum.
Set within its surrounding area, walkability runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. The closest healthier ZIP overall is ZIP 95307, 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 1.64 years of 77.4, 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
