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 1.7% nationally
Lower is healthier
ST88thUS98thDefinition & 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 ›Distance to a Superfund site
114.6 mi
in the top 2.9% nationally
Higher is healthier
ST63rdUS97thDefinition & 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
99.6%
in the top 3.2% nationally
Higher is healthier
ST82ndUS97thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Fine-particle (PM2.5) exceedance
1.4%
in the top 6.9% nationally
Lower is healthier
ST89thUS93rdDefinition & 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 ›Short sleep
29.5%
in the bottom 7.5% nationally
Lower is healthier
ST49thUS7thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Outer-floodplain exposure
3.6%
in the top 9.6% nationally
Lower is healthier
ST71stUS90thDefinition & 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 ›Lead in tap water
5 ppb
in the top 10.0% nationally
Lower is healthier
US90thDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
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 ›Floodplain exposure
18.5%
in the top 20% nationally
Lower is healthier
ST90thUS80thDefinition & 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 ›PFAS in drinking water
39%
in the top 24% nationally
Lower is healthier
ST93rdUS76thDefinition & 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 ›Dry extreme heat
12.8 days/year
in the top 31% nationally
Lower is healthier
ST7thUS69thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›The read
Estelline, South Dakota (ZIP 57234) ranks in the top 26% healthiest ZIPs nationally (8,306th) and the top 28% of South Dakota (99th).
A profile of give and take, with clear readings each way: distance to a Superfund site resides in the top 2.9% nationally, and fiber broadband stands in the top 3.2% nationally. Modeled short sleep sits in the bottom 7.5% nationally. Distance to a nursing home resides at the national minimum, shared with about 27% of ZIPs. On the other side, modeled radon stands in the top 1.7% nationally, modeled fine-particle sits in the top 6.9% nationally, and outer-floodplain exposure resides in the top 9.6% nationally. Lead in tap water stands in the top 10.0% nationally, distance to an emergency room sits in the top 10.2% nationally, and distance to a community health center resides in the top 11.7% nationally.
Against its neighbors, outer-floodplain exposure runs far higher 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. The closest ZIP that ranks healthier overall is ZIP 57212, 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 1.71 years of 86.1, 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.
