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 pCi/L
in the top 2.0% nationally
Lower is healthier
ST77thUS98thDefinition & 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 ›Lithium in drinking water
180 µg/L
in the top 0.7% nationally
Lower is healthier
ST96thUS99thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Binge drinking
20.6%
in the top 4.2% nationally
Lower is healthier
ST71stUS96thDefinition & 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 ›Expected annual disaster loss
$0
in the top 4.2% nationally
Lower is healthier
ST99thUS96thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›Transit access
4.6 per 1,000 residents
in the top 5.8% nationally
Higher is healthier
ST96thUS94thDefinition & source ›
The number of public-transit stops 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 ›Natural-disaster risk
in the top 6.9% nationally
Lower is healthier
ST98thUS93rdDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
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 ›PFOA in drinking water
86.7%
in the top 9.9% nationally
Lower is healthier
ST96thUS90thDefinition & source ›
The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›PFOS in drinking water
86.7%
in the top 10.2% nationally
Lower is healthier
ST99thUS90thDefinition & source ›
The share of residents served by public water systems where PFOS, one of the most common “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Subsidized affordable housing

The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›The read
By its overall health score, ZIP 51106, one of several in Sioux City, Iowa lands in the top 40% healthiest ZIPs nationally (12,981st) and the top 50% of Iowa (460th).
The measures split the difference for this area: transit is in the top 5.8% nationally, and fatal road crashes stands in the bottom 12.7% nationally. Against that, modeled radon settles in the top 2.0% nationally, and lithium in drinking water lies in the top 0.7% nationally. Modeled binge drinking resides in the top 4.2% nationally, expected annual loss lands in the top 4.2% nationally, and disaster risk registers in the top 6.9% nationally. Modeled fine-particle sits in the top 8.6% nationally, PFOA in drinking water rests in the top 9.9% nationally, and PFOS in drinking water is in the top 10.2% nationally.
Weighed against the ZIPs nearby, expected annual loss 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. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Overall, the nearest healthier neighbor is ZIP 51007, 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 0.64 years of 79.0, 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
