Crowded housing

Lower is healthier
ST99thUS99thDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.

ST66thUS97thDefinition & 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
Judged by its overall standing, Erwin, South Dakota (ZIP 57233) sits in the top 27% healthiest ZIPs nationally (8,568th) and the top 29% of South Dakota (106th).
An even profile, with readings pulling both ways: modeled short sleep lies in the bottom 1.0% nationally, modeled transportation noise registers at the national minimum, and poverty is at the national minimum. Distance to a Superfund site lies in the top 2.7% nationally, and modeled colon screening registers in the top 4.2% nationally. Unemployment is at the national minimum, shared with about 15% of ZIPs. Households without a vehicle lies at the national minimum, shared with about 16% of ZIPs. Against that, crowded housing registers in the top 0.3% nationally, and modeled radon is in the top 3.5% nationally. Modeled fine-particle lies in the top 6.9% nationally.
Placed beside its immediate neighbors, crowded housing runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. A healthier nearby ZIP overall is ZIP 57212, about 1.0 miles away.

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 1.55 years of 78.8, 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.
