Radon
3.7 pCi/L
in the top 3.2% nationally
Lower is healthier
ST68thUS97thDefinition & 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.

Full methodology ›The read
By the composite health measure, Carthage, South Dakota (ZIP 57323) ranks in the top 40% healthiest ZIPs nationally (12,669th) and the bottom 40% of South Dakota (215th).
The picture here is genuinely mixed, with readings on both sides: modeled transportation noise lies at the national minimum, and distance to a Superfund site lands in the top 3.3% nationally. Modeled short sleep sits in the bottom 6.5% nationally. Unemployment is at the national minimum, shared with about 15% of ZIPs. Fiber broadband settles in the top 9.2% nationally, and distance to a hazardous-chemical facility resides in the top 9.6% nationally. On the other side, modeled radon registers in the top 3.2% nationally, slow internet speeds rests in the top 4.3% nationally, and walkability stands in the bottom 5.7% nationally. Modeled fine-particle lies in the top 10.5% nationally.
Read against the ZIPs closest to it, slow internet speeds runs far higher than the surrounding ZIPs on this measure. To spell things out, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Close by, ZIP 57231, just across the boundary, ranks healthier overall.

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 1.00 years of 79.5, 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.
