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.

East New Market, Maryland (ZIP 21631), on the composite measure, lands in the top 36% healthiest ZIPs nationally (11,408th) and the bottom 28% of Maryland (331st), based on limited data; treat as directional.
What works most in this area's favor shows up clearly across the measures: modeled mammography settles in the top 6.4% nationally. Crowded housing stands at the national minimum, shared with about 29% of ZIPs. Modeled pfas is in the bottom 17% nationally, and poverty rests in the bottom 18% nationally. Modeled colon screening sits in the top 16% nationally, and households without a vehicle registers in the bottom 21% nationally. Working the other way, fatal road crashes lands in the top 6.5% nationally. Distance to a hazardous-chemical facility resides at the national minimum, shared with about 31% of ZIPs. Recreation lies at the national minimum, shared with about 35% of ZIPs. Physicians settles at the national minimum, shared with about 38% of ZIPs.
Set against the neighboring ZIPs, park land runs far lower 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. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. A healthier neighbor overall sits at ZIP 21673, 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 79.8, 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.
