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
5.3 pCi/L
in the top 0.2% nationally
Lower is healthier
ST98thUS99thDefinition & 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 ›Child-care access
1.5 per 1,000 residents
in the top 0.7% nationally
Higher is healthier
ST98thUS99thDefinition & source ›
The number of child day-care services inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Arsenic in groundwater
35.5%
in the top 2.2% nationally
Lower is healthier
ST96thUS98thDefinition & 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 ›Fine-particle (PM2.5) exceedance
1.1%
in the top 8.6% nationally
Lower is healthier
ST97thUS91stDefinition & 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 ›Distance to a community health center
18.2 mi
in the top 9.4% nationally
Lower is healthier
ST73rdUS91stDefinition & 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.
Full methodology ›Binge drinking
19.2%
in the top 9.8% nationally
Lower is healthier
ST36thUS90thDefinition & 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 ›Dental provider access
0.77 per 1,000 residents
in the top 11.9% nationally
Higher is healthier
ST93rdUS88thDefinition & source ›
The number of dental offices located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Tree cover

The share of this ZIP’s land area covered by forest.

The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.

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
On the composite measure, Primghar, Iowa (ZIP 51245) stands in the bottom 41% nationally (19,076th) and the bottom 14.5% of Iowa (789th).
The weightiest signals in the profile are worth naming up front: modeled radon is in the top 0.2% nationally, and arsenic registers in the top 2.2% nationally. Modeled fine-particle lies in the top 8.6% nationally, and distance to a community health center is in the top 9.4% nationally. Modeled binge drinking registers in the top 9.8% nationally. More positively, childcare lies in the top 0.7% nationally. Modeled loud transportation noise is at the national minimum, shared with about 22% of ZIPs. Modeled transportation noise registers in the bottom 11.8% nationally, and dental providers lies in the top 11.9% nationally. Crowded housing is at the national minimum, shared with about 29% of ZIPs.
Set beside the wider area around it, childcare runs far higher than the surrounding ZIPs on this measure. For clarity, 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. ZIP 51046, just across the boundary, ranks better overall among the ZIPs nearby.

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 1.39 years of 78.4, 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
