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 ›Fiber broadband
100%
at the national maximum
Higher is healthier
ST99thUS99thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Fatal road crashes
65.5 per 100,000 residents per year
in the top 1.7% nationally
Lower is healthier
ST97thUS98thDefinition & 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 ›Distance to a Superfund site
118.6 mi
in the top 2.8% nationally
Higher is healthier
ST66thUS97thDefinition & 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 ›Outpatient-care access
0.79 per 1,000 residents
in the top 3.2% nationally
Higher is healthier
ST95thUS97thDefinition & source ›
The number of outpatient clinics 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
1.5 intersections/sq mi
in the bottom 4.7% nationally
Higher is healthier
ST43rdUS5thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Floodplain exposure
0.04%
in the bottom 7.1% nationally
Lower is healthier
ST10thUS7thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Short sleep
29.4%
in the bottom 7.1% nationally
Lower is healthier
ST46thUS7thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Industrial-pollution burden
in the bottom 9.6% nationally
Lower is healthier
ST14thUS10thDefinition & 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 ›The read
Plankinton, South Dakota (ZIP 57368) ranks in the top 31% healthiest ZIPs nationally (9,924th) and the top 38% of South Dakota (135th).
Several signals sit on each side of the ledger here: fiber broadband lies at the national maximum, and distance to a Superfund site is in the top 2.8% nationally. Outpatient registers in the top 3.2% nationally, and floodplain exposure lies in the bottom 7.1% nationally. Modeled short sleep is in the bottom 7.1% nationally, and industrial-pollution burden registers in the bottom 9.6% nationally. Distance to a community health center lies at the national minimum, shared with about 23% of ZIPs. Working the other way, modeled radon is in the top 1.6% nationally, fatal road crashes registers in the top 1.7% nationally, and walkability lies in the bottom 4.7% nationally.
Against its neighbors, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. For context, 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 ZIP that ranks healthier overall is ZIP 57312, about 12 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 1.76 years of 83.5, 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.
