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
ZIP 95928, one of several in Chico, California ranks in the bottom 36% nationally (20,387th) and the bottom 28% of California (1,243rd).
The weightiest signals in the profile are worth naming up front: modeled air-toxics cancer risk settles in the top 0.4% nationally, and fine-particle rests in the top 1.7% nationally. Modeled disaster risk lands in the top 3.1% nationally, and loud transportation noise settles in the top 3.4% nationally. Modeled extreme heat rests in the top 5.5% nationally, homeownership lands in the bottom 5.9% nationally, and housing-cost burden settles in the top 6.7% nationally. Modeled expected annual loss rests in the top 7.4% nationally, and floodplain exposure lands in the top 8.0% nationally. More positively, subsidized affordable housing settles in the top 4.0% nationally.
Against its neighbors, expected annual loss runs far higher than the surrounding ZIPs on this measure. For context, 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. The closest ZIP that ranks healthier overall is ZIP 95926, 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 0.64 years of 78.9, 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
