What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Energy-cost burden
9.5%
in the top 0.5% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.

Higher is healthier
ST99thUS99thDefinition & 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 ›Radon

ST65thUS96thDefinition & 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
In overall standing, Onaka, South Dakota (ZIP 57466) comes out in the bottom 36% nationally (20,643rd) and the bottom 18% of South Dakota (295th), based on limited data; treat as directional.
The data is direct about where this area carries real strain: modeled energy burden resides in the top 0.5% nationally, modeled radon rests in the top 3.6% nationally, and slow internet speeds lies in the top 2.2% nationally. Distance to a community health center sits in the top 2.5% nationally, walkability settles in the bottom 3.5% nationally, and crowded housing registers in the top 4.1% nationally. Poverty stands in the top 4.9% nationally. More encouragingly, distance to a Superfund site lands in the top 1.2% nationally, and homeownership is at the national maximum. Unemployment resides at the national minimum, shared with about 15% of ZIPs.
Relative to the ZIPs around it, slow internet speeds runs far higher than the surrounding ZIPs on this measure. In plain terms, 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. Energy burden is the share of household income that goes to home energy bills. The nearest healthier ZIP overall is ZIP 57471, 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 1.14 years of 81.0, 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.
