Fatal road crashes

ST1stUS1stDefinition & 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.

Full methodology ›The read
Marydel, Delaware (ZIP 19964), on the composite measure, lands in the bottom 23% nationally (24,742nd) and the bottom 4.7% of Delaware (61st).
The profile cuts both ways, and the readings bear that out: fatal road crashes resides at the national minimum, and housing-cost burden lies in the bottom 5.8% nationally. Modeled loud transportation noise settles at the national minimum, shared with about 22% of ZIPs. Crowded housing stands at the national minimum, shared with about 29% of ZIPs. Distance to a hazardous-chemical facility is in the top 14.7% nationally. Working the other way, households without a vehicle rests in the top 3.3% nationally, and home broadband subscription sits in the bottom 5.5% nationally. Modeled mammography registers in the bottom 10.1% nationally, and distance to a nursing home lands in the top 13.5% nationally. Modeled obesity resides in the top 11.7% nationally.
Set against the neighboring ZIPs, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. In everyday language, 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. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. A healthier neighbor overall sits at ZIP 19934, 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 1.25 years of 74.5, 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
