Full methodology ›The read
Chelsea, Michigan (ZIP 48118), by its composite score, sits in the top 6.2% healthiest ZIPs nationally (1,981st) and the top 4.7% of Michigan (45th).
The measures fall on both sides for this area, fairly evenly: modeled short sleep sits in the bottom 0.2% nationally, and housing insecurity lies in the bottom 2.4% nationally. Modeled food insecurity rests in the bottom 2.9% nationally, and transportation resides in the bottom 3.8% nationally. Physicians is in the top 4.2% nationally, and modeled colon screening lands in the top 2.9% nationally. Distance to an emergency room stands at the national minimum, shared with about 11% of ZIPs. Modeled utility shutoff registers in the bottom 5.7% nationally, and loneliness settles in the bottom 5.9% nationally. Pulling the other way, modeled arsenic sits in the top 2.0% nationally.
Next to the surrounding area, arsenic runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark.

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 0.65 years of 82.2, 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
