Willis, Michigan (ZIP 48191), by its overall standing, sits in the top 16% healthiest ZIPs nationally (5,072nd) and the top 13.3% of Michigan (129th).
Several good marks anchor the profile and deserve first mention: modeled short sleep sits in the bottom 2.9% nationally. Households without a vehicle settles at the national minimum, shared with about 16% of ZIPs. Modeled disaster risk registers in the bottom 8.8% nationally, and high cholesterol stands in the bottom 7.9% nationally. Crowded housing lands at the national minimum, shared with about 29% of ZIPs. Modeled fair or poor health is in the bottom 13.2% nationally, and homeownership resides in the top 16% nationally. By contrast, outer-floodplain exposure rests in the top 7.9% nationally. Fiber broadband lies at the national minimum, shared with about 19% of ZIPs. Modeled pfas sits in the top 13.5% nationally.
Held up against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. 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. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". The nearest ZIP ranking healthier overall is ZIP 48176, about 4.8 miles away.

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 77.0, 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
