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
On what the available sources can show, Grantham, Pennsylvania (ZIP 17027) lands in the top 14.7% healthiest ZIPs nationally (4,707th) and the top 11.7% of Pennsylvania (204th), based on limited data; treat as directional.
Where the data reaches, it shows a few things about this area: fatal road crashes registers at the national minimum, and home broadband subscription rests in the top 6.0% nationally. Households without a vehicle stands at the national minimum, shared with about 16% of ZIPs. Modeled tooth loss lies in the bottom 7.8% nationally. By contrast, modeled loud transportation noise lands in the top 0.5% nationally, slow internet speeds sits in the top 1.2% nationally, and modeled transportation noise is in the top 5.9% nationally. Outer-floodplain exposure settles in the top 10.5% nationally, PFOA in drinking water resides in the top 11.7% nationally, and PFOS in drinking water registers in the top 12.1% nationally.
Read against the ZIPs closest to it, loud transportation noise runs far higher than the surrounding ZIPs on this measure. To spell things out, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. 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. Close by, ZIP 17007, about 2.8 miles away, ranks healthier overall.
What’s driving this score

Not placed: Chronic Disease Burden and Risk Behavior — too little of each is measured here to compare reliably. They still count toward the score (together 38% of it); we just will not publish a standing we cannot stand behind.
No data: Mental Health and Disability — not measured in this ZIP, so it is left out of the score entirely rather than estimated.

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.
