Floodplain exposure

ST1stUS1stDefinition & source ›
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.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

Overall, Interlochen, Michigan (ZIP 49643) places in the top 24% healthiest ZIPs nationally (7,843rd) and the top 22% of Michigan (211th).
The standout strengths in the data are the natural place to begin: floodplain exposure settles at the national minimum, and park land sits in the top 3.9% nationally. Modeled industrial-pollution burden lies in the bottom 9.3% nationally, and short sleep rests in the bottom 16% nationally. Modeled tooth loss resides in the bottom 13.0% nationally. Outer-floodplain exposure is at the national minimum, shared with about 36% of ZIPs. Modeled colon screening lands in the top 18% nationally. On the other side, modeled pfas stands in the top 14.4% nationally, disaster risk registers in the top 18% nationally, and expected annual loss settles in the top 19% nationally.
Beside the areas that surround it, park land runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Among nearby ZIPs, the nearest healthier one overall is ZIP 49650, 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 0.58 years of 78.0, 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
