What defines this ZIP

Fiber broadband
100%

Higher is healthier
ST99thUS99thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Radon
3.7 pCi/L
in the top 3.6% nationally
Lower is healthier
ST64thUS96thDefinition & 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 ›Distance to a Superfund site
126.2 mi
in the top 2.5% nationally
Higher is healthier
ST72ndUS98thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Outer-floodplain exposure
9.6%
in the top 3.9% nationally
Lower is healthier
ST93rdUS96thDefinition & 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.
Full methodology ›Homeownership rate
97.4%
in the top 6.2% nationally
Higher is healthier
ST94thUS94thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.
Full methodology ›Short sleep

ST39thUS6thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.

Full methodology ›The read
Cavour, South Dakota (ZIP 57324) ranks in the top 24% healthiest ZIPs nationally (7,701st) and the top 24% of South Dakota (86th).
A balanced set of signals defines this area, not any single one: fiber broadband rests at the national maximum, and distance to a Superfund site lands in the top 2.5% nationally. Homeownership settles in the top 6.2% nationally, and modeled short sleep rests in the bottom 6.2% nationally. Unemployment lands at the national minimum, shared with about 15% of ZIPs. Households without a vehicle settles at the national minimum, shared with about 16% of ZIPs. Housing-cost burden rests in the bottom 9.1% nationally. By contrast, modeled radon lands in the top 3.6% nationally, outer-floodplain exposure settles in the top 3.9% nationally, and lithium in drinking water rests in the top 11.5% nationally.
Against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For context, 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. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. The closest ZIP that ranks healthier overall is ZIP 57386, 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 1.72 years of 78.4, 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.
