Fatal road crashes

ST99thUS99thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.

ST21stUS9thDefinition & source ›
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
Willow Creek, California (ZIP 95573) ranks in the bottom 27% nationally (23,504th) and the bottom 21% of California (1,353rd).
Several readings make the pressure on this area plain: fatal road crashes settles in the top 0.3% nationally, and modeled fine-particle rests in the top 0.9% nationally. Housing-cost burden lands in the top 2.5% nationally, and distance to a nursing home settles in the top 3.2% nationally. Modeled air-toxics cancer risk rests in the top 7.6% nationally. On the encouraging side, civic lands in the top 3.2% nationally, pharmacy settles in the top 3.9% nationally, and modeled tree cover rests in the top 4.6% nationally. Distance to a hazardous-chemical facility lands in the top 8.8% nationally, and floodplain exposure settles in the bottom 9.0% nationally.
Against its neighbors, fatal road crashes runs far higher than the surrounding ZIPs on this measure. For context, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. The closest ZIP that ranks healthier overall is ZIP 95525, 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 78.2, 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
