Radon
3.8 pCi/L
in the top 2.9% nationally
Lower is healthier
ST69thUS97thDefinition & 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 ›Binge drinking
20.7%
in the top 3.9% nationally
Lower is healthier
ST74thUS96thDefinition & 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 ›PFAS in drinking water
7.5%
in the bottom 4.2% nationally
Lower is healthier
ST12thUS4thDefinition & 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 ›Housing-cost burden

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.

ST6thUS19thDefinition & 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.

The read
On balance, and by the composite measure, Gilman, Iowa (ZIP 50106) ranks in the top 28% healthiest ZIPs nationally (9,062nd) and the top 26% of Iowa (243rd).
Neither strongly one way nor the other, the measures sit mixed: modeled pfas stands in the bottom 4.2% nationally, and housing-cost burden settles in the bottom 5.9% nationally. Fiber broadband lies in the top 8.5% nationally, and homeownership resides in the top 13.2% nationally. Modeled housing insecurity lands in the bottom 13.3% nationally. Against that, modeled radon registers in the top 2.9% nationally, binge drinking sits in the top 3.9% nationally, and arsenic rests in the top 6.5% nationally. Modeled loud transportation noise is in the top 8.9% nationally, and walkability stands in the bottom 12.4% nationally.
In plainer terms, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. For a healthier nearby ZIP overall, look to ZIP 50078, 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 2.07 years of 84.1, 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.
