Full methodology ›The read
Judged by its overall standing, Greenfield, California (ZIP 93927) sits in the bottom 25% nationally (24,110th) and the bottom 20% of California (1,375th).
A demanding profile, and several measures drive it: modeled uninsured registers in the top 1.6% nationally, modeled colon screening is in the bottom 1.9% nationally, and crowded housing lies in the top 0.7% nationally. Modeled disaster risk registers in the top 1.0% nationally, fair or poor health is in the top 3.0% nationally, and housing insecurity lies in the top 1.7% nationally. Modeled vision disability registers in the top 4.3% nationally, and cognitive disability is in the top 3.3% nationally. Modeled nitrate lies in the top 2.3% nationally. On the stronger side, modeled industrial-pollution burden registers in the bottom 0.9% nationally.
Placed beside its immediate neighbors, crowded housing runs far higher than the surrounding ZIPs on this measure. Put plainly, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. 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 93924, 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 35.8; chronic-disease standing 88.8 — 53 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 1.79 years of 81.5, 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
