Definition & 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.

The measures that define this area's challenges come through directly: fatal road crashes rests in the top 0.07% nationally, and crowded housing resides in the top 0.4% nationally. Modeled colon screening is in the bottom 2.0% nationally, and housing-cost burden lands in the top 1.0% nationally. Unemployment stands in the top 1.5% nationally, modeled nitrate registers in the top 2.1% nationally, and modeled uninsured settles in the top 5.4% nationally. Homeownership sits in the bottom 4.7% nationally, and modeled tree cover lies at the national minimum. On the stronger side, home broadband subscription rests at the national maximum.

Beside the areas that surround it, fatal road crashes runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Among nearby ZIPs, the nearest healthier one overall is ZIP 95304, just across the boundary.

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 19.6; chronic-disease standing 91.6 (top 10%) — 72 points apart, heavier on the environment than it is on chronic illness.

    Ranked #16,570 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 2.13 years of 80.9, 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.
