Radon
4.4 pCi/L
in the top 0.9% nationally
Lower is healthier
ST97thUS99thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.

Lower is healthier
ST97thUS98thDefinition & source ›
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.
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.

Lower is healthier
ST99thUS96thDefinition & 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.

Full methodology ›The read
Overall, Gayville, South Dakota (ZIP 57031) places in the top 43% healthiest ZIPs nationally (13,888th) and the bottom 35% of South Dakota (235th).
The measures land in both directions, and neither dominates: unemployment rests at the national minimum, shared with about 15% of ZIPs. Housing-cost burden resides in the bottom 8.2% nationally, and modeled short sleep is in the bottom 8.3% nationally. Distance to a Superfund site lands in the top 13.5% nationally, and households without a vehicle stands in the bottom 17% nationally. Pulling the other way, modeled radon registers in the top 0.9% nationally, outer-floodplain exposure settles in the top 1.8% nationally, and floodplain exposure sits in the top 4.2% nationally. Modeled fine-particle lies in the top 11.7% nationally, and extreme heat rests in the top 15% nationally.
Beside the areas that surround it, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Among nearby ZIPs, the nearest healthier one overall is ZIP 57046, 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 1.52 years of 82.9, 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.
