The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.

The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.

Flat Rock, Michigan (ZIP 48134), by its overall standing, sits in the top 34% healthiest ZIPs nationally (11,029th) and the top 33% of Michigan (319th).
Several readings land clearly in this area's favor and shape the picture: park land settles in the top 11.6% nationally, fatal road crashes registers in the bottom 16% nationally, and subsidized affordable housing stands in the top 17% nationally. Mental-health providers lands in the top 21% nationally. Set against that, outer-floodplain exposure is in the top 6.7% nationally, and distance to a Superfund site resides in the bottom 11.5% nationally. Modeled industrial-pollution burden rests in the top 16% nationally, and unemployment lies in the top 19% nationally. Modeled expected annual loss sits in the top 22% nationally, and floodplain exposure settles in the top 22% nationally.
Held up against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. The nearest ZIP ranking healthier overall is ZIP 48173, just across the boundary.

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 1.26 years of 76.2, 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.
