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.

Full methodology ›The read
Overall, Kranzburg, South Dakota (ZIP 57245) places in the top 25% healthiest ZIPs nationally (8,076th) and the top 27% of South Dakota (97th).
The measures fall on both sides for this area, fairly evenly: fiber broadband registers at the national maximum, and modeled disaster risk settles in the bottom 1.8% nationally. Distance to a Superfund site sits in the top 2.5% nationally, and floodplain exposure lies at the national minimum. Modeled expected annual loss rests in the bottom 3.2% nationally. Unemployment resides at the national minimum, shared with about 15% of ZIPs. Modeled mammography is in the top 4.9% nationally. Pulling the other way, distance to a community health center lands in the top 2.1% nationally, modeled radon stands in the top 5.1% nationally, and modeled fine-particle registers in the top 6.9% nationally.
Beside the areas that surround it, walkability runs far higher than the surrounding ZIPs on this measure. For readers new to these 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Among nearby ZIPs, the nearest healthier one overall is ZIP 57218, about 17 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 3.03 years of 87.6, 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.
