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.
Radon
4.1 pCi/L
in the top 1.6% nationally
Lower is healthier
ST89thUS98thDefinition & 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 ›Pharmacy access
0.85 per 1,000 residents
in the top 1.5% nationally
Higher is healthier
ST96thUS99thDefinition & 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 ›Distance to a Superfund site
120.4 mi
in the top 2.7% nationally
Higher is healthier
ST67thUS97thDefinition & 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 ›Fiber broadband
99.2%
in the top 4.4% nationally
Higher is healthier
ST71stUS96thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Short sleep
28.3%
in the bottom 3.8% nationally
Lower is healthier
ST18thUS4thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Civic-institution access
0.85 per 1,000 residents
in the top 5.7% nationally
Higher is healthier
ST89thUS94thDefinition & source ›
The number of civic and social organizations 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 ›PFAS in drinking water
46%
in the top 16% nationally
Lower is healthier
ST96thUS84thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›The read
Woonsocket, South Dakota (ZIP 57385), on the composite measure, lands in the top 37% healthiest ZIPs nationally (11,836th) and the bottom 48% of South Dakota (187th), based on limited data; treat as directional.
Where the data leans one way, another reading answers it: pharmacy sits in the top 1.5% nationally, distance to a Superfund site registers in the top 2.7% nationally, and fiber broadband lands in the top 4.4% nationally. Modeled short sleep resides in the bottom 3.8% nationally, and civic lies in the top 5.7% nationally. Distance to a community health center settles at the national minimum, shared with about 23% of ZIPs. On the other hand, modeled radon stands in the top 1.6% nationally, and lithium in drinking water is in the top 11.4% nationally. Modeled fine-particle rests in the top 11.7% nationally, and slow internet speeds sits in the top 13.1% nationally.
In everyday language, 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. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. A healthier neighbor overall sits at ZIP 57312, 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 1.04 years of 79.7, 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.
