Full methodology ›The read
In its overall standing, Amasa, Michigan (ZIP 49903) lands in the top 48% healthiest ZIPs nationally (15,305th) and the top 47% of Michigan (460th), based on limited data; treat as directional.
This area's measures are easy to read as a mixed set: distance to a hazardous-chemical facility lies in the top 1.4% nationally, modeled air-toxics cancer risk stands in the bottom 2.8% nationally, and modeled humid heat rests in the bottom 5.9% nationally. Distance to a Superfund site registers in the top 11.6% nationally. Set against that, slow internet speeds resides in the top 1.9% nationally, and home broadband subscription settles in the bottom 4.5% nationally. Walkability is in the bottom 5.2% nationally, and households without a vehicle sits in the top 9.3% nationally. Fiber broadband lands at the national minimum, shared with about 19% of ZIPs. Modeled fine-particle lies in the top 9.7% nationally.
Against the wider neighborhood, slow internet speeds runs far higher than the surrounding ZIPs on this measure. Put simply, 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. On the overall standing, ZIP 49961, about 3.0 miles away, ranks healthier.

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 1.00 years of 78.8, 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.
