Full methodology ›The read
In its overall standing, South Lyon, Michigan (ZIP 48178) lands in the top 6.5% healthiest ZIPs nationally (2,055th) and the top 5.0% of Michigan (48th).
This area's most favorable readings come through plainly in the numbers: household income stands in the top 6.7% nationally, modeled housing insecurity rests in the bottom 6.7% nationally, and modeled transportation registers in the bottom 6.7% nationally. Lithium in drinking water resides in the bottom 6.8% nationally, modeled food insecurity settles in the bottom 7.8% nationally, and modeled short sleep is in the bottom 7.9% nationally. Modeled fair or poor health sits in the bottom 6.3% nationally, and mobility disability lands in the bottom 7.2% nationally. On the other side, distance to a Superfund site lies in the bottom 6.8% nationally, and modeled expected annual loss stands in the top 7.4% nationally.
Against the wider neighborhood, park land runs far lower than the surrounding ZIPs on this measure. Put simply, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. On the overall standing, ZIP 48105, just across the boundary, 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 0.47 years of 80.4, 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.
