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
4.5 pCi/L
in the top 0.8% nationally
Lower is healthier
ST88thUS99thDefinition & 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 ›Floodplain exposure
54.8%
in the top 3.3% nationally
Lower is healthier
ST99thUS97thDefinition & 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 ›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 ›Arsenic in groundwater
22.9%
in the top 5.2% nationally
Lower is healthier
ST86thUS95thDefinition & 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 ›Fiber broadband
97.6%
in the top 7.3% nationally
Higher is healthier
ST77thUS93rdDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Fine-particle (PM2.5) exceedance

ST92ndUS90thDefinition & 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 ›Home broadband subscription

in the bottom 9.8% nationally

ST6thUS10thDefinition & source ›
The share of households with a broadband internet subscription.

The share of occupied homes that are owned, rather than rented, by the people living in them.

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
In its overall standing, Hornick, Iowa (ZIP 51026) lands in the top 43% healthiest ZIPs nationally (13,649th) and the bottom 45% of Iowa (506th).
This area's measures are easy to read as a mixed set: fiber broadband resides in the top 7.3% nationally, and homeownership settles in the top 10.9% nationally. Modeled loud transportation noise is at the national minimum, shared with about 22% of ZIPs. Modeled short sleep sits in the bottom 12.4% nationally. Set against that, modeled radon lands in the top 0.8% nationally, and floodplain exposure lies in the top 3.3% nationally. Modeled binge drinking stands in the top 3.9% nationally, and arsenic rests in the top 5.2% nationally. Modeled fine-particle registers in the top 9.6% nationally, and home broadband subscription resides in the bottom 9.8% nationally.
Put 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. On the overall standing, ZIP 51007, just across the boundary, ranks healthier.

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 1.14 years of 80.6, 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
