Radon
3.8 pCi/L
in the top 2.6% nationally
Lower is healthier
ST71stUS97thDefinition & 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 ›PFAS in drinking water
5.8%
in the bottom 1.8% nationally
Lower is healthier
ST4thUS2ndDefinition & 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 ›Energy-cost burden
5.5%
in the top 5.0% nationally
Lower is healthier
ST91stUS95thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Transportation noise
0.04%
in the bottom 6.8% nationally
Lower is healthier
ST11thUS7thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Fiber broadband

in the top 7.9% nationally
Higher is healthier
ST76thUS92ndDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Binge drinking
19.7%
in the top 7.4% nationally
Lower is healthier
ST49thUS93rdDefinition & 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
16.2%
in the top 9.0% nationally
Lower is healthier
ST76thUS91stDefinition & 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 ›Obesity
43.6%
in the top 7.2% nationally
Lower is healthier
ST96thUS93rdDefinition & source ›
The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.

The read
By its overall health score, Thor, Iowa (ZIP 50591) lands in the bottom 30% nationally (22,312th) and the bottom 5.0% of Iowa (876th).
The measures that press hardest set the tone here: modeled radon settles in the top 2.6% nationally, and energy burden lies in the top 5.0% nationally. Modeled binge drinking resides in the top 7.4% nationally, and arsenic lands in the top 9.0% nationally. Modeled obesity registers in the top 7.2% nationally, and tree cover sits in the bottom 10.5% nationally. On the stronger side, modeled pfas rests in the bottom 1.8% nationally, modeled transportation noise is in the bottom 6.8% nationally, and fiber broadband stands in the top 7.9% nationally. Home broadband subscription settles in the top 10.7% nationally.
Weighed against the ZIPs nearby, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. To translate a couple of 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. Overall, the nearest healthier neighbor is ZIP 50516, 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 1.69 years of 81.5, 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. How distance is measured
