Distance to a community health center
69.3 mi
in the top 0.3% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest federally funded community health center, which serves patients regardless of ability to pay.
Full methodology ›Radon
3.6 pCi/L
in the top 4.0% nationally
Lower is healthier
ST61stUS96thDefinition & 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
99.7%
in the top 2.8% nationally
Higher is healthier
ST85thUS97thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Distance to a Superfund site
93.8 mi
in the top 4.0% nationally
Higher is healthier
ST47thUS96thDefinition & 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 ›Outer-floodplain exposure
8.0%
in the top 4.7% nationally
Lower is healthier
ST89thUS95thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›Fine-particle (PM2.5) exceedance
1.6%
in the top 6.1% nationally
Lower is healthier
ST97thUS94thDefinition & 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 ›Lithium in drinking water
63 µg/L
in the top 8.3% nationally
Lower is healthier
ST78thUS92ndDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Natural-disaster risk
in the bottom 12.4% nationally
Lower is healthier
ST9thUS12thDefinition & 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 ›Arsenic in groundwater
6.6%
in the top 28% nationally
Lower is healthier
ST92ndUS72ndDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
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
On balance, and by the composite measure, Corona, South Dakota (ZIP 57227) ranks in the top 45% healthiest ZIPs nationally (14,545th) and the bottom 32% of South Dakota (245th).
The measures split the difference for this area: fiber broadband sits in the top 2.8% nationally, and distance to a Superfund site rests in the top 4.0% nationally. Modeled loud transportation noise is at the national minimum, shared with about 22% of ZIPs. Modeled disaster risk stands in the bottom 12.4% nationally. Against that, distance to a community health center settles in the top 0.3% nationally, modeled radon lies in the top 4.0% nationally, and outer-floodplain exposure resides in the top 4.7% nationally. Modeled fine-particle lands in the top 6.1% nationally, lithium in drinking water registers in the top 8.3% nationally, and distance to an emergency room sits in the top 13.3% nationally.
Compared with the ZIPs it borders, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. In plainer 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. For a healthier nearby ZIP overall, look to ZIP 56225, 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 1.60 years of 81.3, 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.
