By the composite health measure, ZIP 48331, one of several in Farmington, Michigan ranks in the top 2.0% healthiest ZIPs nationally (620th) and the top 1.6% of Michigan (15th).
A number of measures place this area on solid footing: modeled colon screening lies in the top 1.9% nationally, and lead in tap water lands at the national minimum. Outpatient sits in the top 4.9% nationally, and modeled cognitive disability is in the bottom 2.8% nationally. Civic settles in the top 5.0% nationally, physicians resides in the top 5.1% nationally, and modeled transportation registers in the bottom 5.9% nationally.

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 0.86 years of 82.0, 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
