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 1.8% nationally
Lower is healthier
ST87thUS98thDefinition & 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
1.3 per 1,000 residents
in the top 1.2% nationally
Higher is healthier
ST95thUS99thDefinition & 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 ›Fatal road crashes
57.6 per 100,000 residents per year
in the top 2.6% nationally
Lower is healthier
ST95thUS97thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Outer-floodplain exposure
9.4%
in the top 4.0% nationally
Lower is healthier
ST92ndUS96thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›Distance to a Superfund site
85.1 mi
in the top 4.7% nationally
Higher is healthier
ST41stUS95thDefinition & 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 ›Fiber broadband
98.1%
in the top 6.5% nationally
Higher is healthier
ST55thUS94thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Poverty rate

Lower is healthier
ST15thUS8thDefinition & source ›
The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.
Full methodology ›Civic-institution access
0.66 per 1,000 residents
in the top 8.4% nationally
Higher is healthier
ST86thUS92ndDefinition & source ›
The number of civic and social organizations 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 ›Housing-cost burden

The share of households spending 30% or more of their income on housing.

Full methodology ›The read
Alexandria, South Dakota (ZIP 57311), overall, ranks in the top 38% healthiest ZIPs nationally (12,091st) and the bottom 46% of South Dakota (196th).
This area's measures are easy to read as a mixed set: childcare lands in the top 1.2% nationally, distance to a Superfund site lies in the top 4.7% nationally, and fiber broadband stands in the top 6.5% nationally. Poverty rests in the bottom 8.2% nationally, civic registers in the top 8.4% nationally, and housing-cost burden resides in the bottom 8.8% nationally. Modeled short sleep settles in the bottom 12.4% nationally. Set against that, modeled radon is in the top 1.8% nationally, and fatal road crashes sits in the top 2.6% nationally. Outer-floodplain exposure lands in the top 4.0% nationally.
Measured against the nearby ZIPs, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined simply, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". ZIP 57301, just across the boundary, comes out healthier overall.

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 0.96 years of 79.1, 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.
