Energy-cost burden

ST94thUS99thDefinition & 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.

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.

Full methodology ›The read
Overall, Rockham, South Dakota (ZIP 57470) lands in the bottom 47% nationally (16,958th) and the bottom 23% of South Dakota (278th), based on limited data; treat as directional.
Several measures weigh most on this area's profile, and they come first: modeled energy burden settles in the top 1.2% nationally, and crowded housing resides in the top 0.5% nationally. Poverty registers in the top 1.0% nationally, and walkability rests in the bottom 2.4% nationally. Modeled radon stands in the top 6.0% nationally, distance to a community health center lies in the top 4.6% nationally, and modeled hearing disability lands in the top 8.0% nationally. On the better side, distance to a Superfund site sits in the top 1.3% nationally, and homeownership is at the national maximum. Households without a vehicle settles at the national minimum, shared with about 16% of ZIPs.
Set beside the nearby areas, crowded housing runs far higher than the surrounding ZIPs on this measure. A note on the 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. For a healthier nearby comparison, ZIP 57373, 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 1.89 years of 81.8, 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.
