ST98thUS99thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.

ST97thUS99thDefinition & 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 ›The read
In its overall standing, ZIP 91761, one of several in Ontario, California lands in the bottom 49% nationally (16,314th) and the bottom 38% of California (1,072nd).
This area's pressures are easy to read across the measures: modeled disaster risk lies in the top 0.6% nationally, outer-floodplain exposure stands in the top 1.0% nationally, and modeled air-toxics cancer risk rests in the top 1.7% nationally. Modeled loud transportation noise registers in the top 2.3% nationally, colon screening resides in the bottom 4.0% nationally, and transportation noise settles in the top 2.8% nationally. Modeled expected annual loss is in the top 2.8% nationally, and fine-particle sits in the top 2.9% nationally. Crowded housing lands in the top 3.9% nationally, and modeled tree cover lies at the national minimum.
Against the wider neighborhood, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put simply, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. On the overall standing, ZIP 91752, just across the boundary, ranks healthier.

Findings that name this ZIP
One of our published findings lists 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 0.1 (bottom 1%); chronic-disease standing 91.3 (top 10%) — 91 points apart, heavier on the environment than it is on chronic illness.
Ranked #17,945 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

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

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
