Fiber broadband

The share of homes where fiber-optic internet service is available.

ST71stUS97thDefinition & 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
Overall, Dimock, South Dakota (ZIP 57331) lands in the top 36% healthiest ZIPs nationally (11,581st) and the top 49% of South Dakota (178th), based on limited data; treat as directional.
The signals balance out across the profile, strengths against concerns: fiber broadband resides at the national maximum, and distance to a Superfund site registers in the top 4.1% nationally. Modeled short sleep rests in the bottom 4.9% nationally. Unemployment stands at the national minimum, shared with about 15% of ZIPs. Modeled industrial-pollution burden lies in the bottom 12.5% nationally. Crowded housing lands at the national minimum, shared with about 29% of ZIPs. Set against that, modeled radon sits in the top 3.1% nationally, fine-particle is in the top 11.7% nationally, and extreme heat settles in the top 15.0% nationally. Lithium in drinking water resides in the top 16% nationally.
A note on the terms: 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. For a healthier nearby comparison, ZIP 57366, just across the boundary, ranks better 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 1.42 years of 77.6, 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.
