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
4.3 pCi/L
in the top 1.2% nationally
Lower is healthier
ST94thUS99thDefinition & 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
0.86 per 1,000 residents
in the top 1.5% nationally
Higher is healthier
ST97thUS99thDefinition & 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
81.7 mi
in the top 5.0% nationally
Higher is healthier
ST39thUS95thDefinition & 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
98.2%
in the top 6.4% nationally
Higher is healthier
ST56thUS94thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Slow internet speeds
1.7%
in the top 6.7% nationally
Lower is healthier
ST83rdUS93rdDefinition & source ›
The share of homes whose fastest available download speed is under 10 Mbps.
Full methodology ›Short sleep
29.2%
in the bottom 6.5% nationally
Lower is healthier
ST41stUS6thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Natural-disaster risk
in the top 8.2% nationally
Lower is healthier
ST95thUS92ndDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Fatal road crashes
34.6 per 100,000 residents per year
in the top 9.8% nationally
Lower is healthier
ST87thUS90thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›The read
By its overall health score, Parkston, South Dakota (ZIP 57366) lands in the top 35% healthiest ZIPs nationally (11,319th) and the top 47% of South Dakota (170th), based on limited data; treat as directional.
Strengths and concerns sit side by side across the measures here: pharmacy resides in the top 1.5% nationally, and distance to a Superfund site lands in the top 5.0% nationally. Fiber broadband registers in the top 6.4% nationally, and modeled short sleep sits in the bottom 6.5% nationally. On the other hand, modeled radon rests in the top 1.2% nationally, slow internet speeds is in the top 6.7% nationally, and modeled disaster risk stands in the top 8.2% nationally. Fatal road crashes settles in the top 9.8% nationally, modeled fine-particle lies in the top 10.5% nationally, and distance to a community health center resides in the top 10.8% nationally.
To translate a couple of terms, 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Overall, the nearest healthier neighbor is ZIP 57029, 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 1.17 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.
