Radon
4 pCi/L
in the top 1.8% nationally
Lower is healthier
ST78thUS98thDefinition & 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 ›Short sleep
27.7%
in the bottom 2.5% nationally
Lower is healthier
ST2ndUS2ndDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Binge drinking

Lower is healthier
ST64thUS95thDefinition & source ›
The estimated share of adults who report binge drinking — five or more drinks on one occasion for men, four or more for women.
Full methodology ›Arsenic in groundwater

in the top 7.0% nationally
Lower is healthier
ST83rdUS93rdDefinition & 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.

Combined exposures in this ZIP
More than one environmental exposure stands out in this ZIP. Each is established independently and shown on its own above; they are grouped here for context — not because one causes the other.
USGS models a high likelihood that groundwater arsenic here exceeds 10 µg/L — the level EPA sets as the limit for public water systems — and this area's modeled radon runs above EPA's 4 pCi/L action level.

The read
Redfield, Iowa (ZIP 50233), overall, ranks in the top 19% healthiest ZIPs nationally (6,237th) and the top 11.3% of Iowa (104th).
This area's measures are easy to read as a mixed set: modeled short sleep lands in the bottom 2.5% nationally, loneliness lies in the bottom 9.6% nationally, and mammography stands in the top 7.1% nationally. Modeled loud transportation noise rests at the national minimum, shared with about 22% of ZIPs. Modeled housing insecurity registers in the bottom 11.4% nationally, and housing-cost burden resides in the bottom 11.6% nationally. Set against that, modeled radon settles in the top 1.8% nationally, and binge drinking is in the top 5.2% nationally. Modeled arsenic sits in the top 7.0% nationally, and distance to a community health center lands in the top 7.7% nationally.
Defined simply, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. ZIP 50003, just across the boundary, comes out healthier overall.

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 82.8, 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. How distance is measured
