What defines this ZIP

Radon
4 pCi/L
in the top 1.9% nationally
Lower is healthier
ST85thUS98thDefinition & 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 ›Short sleep
26.5%
in the bottom 1.1% nationally
Lower is healthier
ST2ndUS1stDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Distance to a Superfund site
109.3 mi
in the top 3.1% nationally
Higher is healthier
ST60thUS97thDefinition & 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 ›Pharmacy access
0.6 per 1,000 residents
in the top 3.4% nationally
Higher is healthier
ST91stUS97thDefinition & source ›
The number of pharmacies located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Walkability
1.8 intersections/sq mi
in the bottom 6.1% nationally
Higher is healthier
ST51stUS6thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Child-care access
0.6 per 1,000 residents
in the top 7.3% nationally
Higher is healthier
ST78thUS93rdDefinition & source ›
The number of child day-care services inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Industrial-pollution burden
in the bottom 9.2% nationally
Lower is healthier
ST14thUS9thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Fiber broadband
96%
in the top 9.4% nationally
Higher is healthier
ST42ndUS91stDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Fine-particle (PM2.5) exceedance
0.99%
in the top 9.6% nationally
Lower is healthier
ST64thUS90thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Physician access
1.2 per 1,000 residents
in the top 16% nationally
Higher is healthier
ST90thUS84thDefinition & source ›
The number of physicians’ offices located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›The read
De Smet, South Dakota (ZIP 57231), in overall standing, comes out in the top 27% healthiest ZIPs nationally (8,605th) and the top 30% of South Dakota (108th).
A balanced showing across the data, with a few readings each side: modeled short sleep sits in the bottom 1.1% nationally, distance to a Superfund site stands in the top 3.1% nationally, and pharmacy resides in the top 3.4% nationally. Distance to an emergency room sits at the national minimum, shared with about 11% of ZIPs. Childcare stands in the top 7.3% nationally. Unemployment resides at the national minimum, shared with about 15% of ZIPs. Modeled industrial-pollution burden sits in the bottom 9.2% nationally, and fiber broadband stands in the top 9.4% nationally. On the other hand, modeled radon resides in the top 1.9% nationally, and walkability sits in the bottom 6.1% nationally.
Defined simply, for reference, 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. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. The closest healthier ZIP overall is ZIP 57233, 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 1.01 years of 79.6, 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.
