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
3.9 pCi/L
in the top 2.4% nationally
Lower is healthier
ST73rdUS98thDefinition & 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 ›Arsenic in groundwater
25.1%
in the top 4.4% nationally
Lower is healthier
ST88thUS96thDefinition & 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 ›Distance to a community health center

ST84thUS94thDefinition & 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.

Higher is healthier
ST99thUS94thDefinition & 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 ›Housing-cost burden

Lower is healthier
ST8thUS7thDefinition & source ›
The share of households spending 30% or more of their income on housing.
Full methodology ›Energy-cost burden
5.1%
in the top 7.9% nationally
Lower is healthier
ST82ndUS92ndDefinition & 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 ›Tree cover
0.06%
in the bottom 13.7% nationally
Higher is healthier
ST7thUS14thDefinition & source ›
The share of this ZIP’s land area covered by forest.

The read
In overall standing, Havelock, Iowa (ZIP 50546) comes out in the bottom 37% nationally (20,342nd) and the bottom 9.8% of Iowa (832nd).
The measures fall on both sides of the ledger for this area: distance to a Superfund site rests in the top 6.5% nationally, housing-cost burden lies in the bottom 7.0% nationally, and modeled pfas sits in the bottom 10.6% nationally. Modeled transportation noise settles in the bottom 11.7% nationally. Set against that, modeled radon registers in the top 2.4% nationally, and arsenic stands in the top 4.4% nationally. Distance to a community health center lands in the top 5.7% nationally, and modeled energy burden is in the top 7.9% nationally. Modeled tree cover resides in the bottom 13.7% nationally. Distance to a hazardous-chemical facility rests at the national minimum, shared with about 31% of ZIPs.
In plain terms, 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 Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The nearest healthier ZIP overall is ZIP 50527, 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 1.33 years of 77.5, 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.
