Unemployment rate
22.6%
in the top 1.6% nationally
Lower is healthier
ST95thUS98thDefinition & source ›
The share of the civilian labor force that is unemployed.
Full methodology ›Radon
3.6 pCi/L
in the top 4.0% nationally
Lower is healthier
ST60thUS96thDefinition & 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.

Higher is healthier
ST80thUS98thDefinition & 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 ›Walkability
1.5 intersections/sq mi
in the bottom 4.7% nationally
Higher is healthier
ST42ndUS5thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

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

The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Lithium in drinking water
67 µg/L
in the top 6.8% nationally
Lower is healthier
ST86thUS93rdDefinition & 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 ›Fine-particle (PM2.5) exceedance
1.4%
in the top 6.9% nationally
Lower is healthier
ST89thUS93rdDefinition & 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 ›Poverty rate

The read
In overall standing, Columbia, South Dakota (ZIP 57433) comes out in the top 18% healthiest ZIPs nationally (5,851st) and the top 10.6% of South Dakota (38th).
Both sides of the picture show up plainly in this area's numbers: distance to a Superfund site settles in the top 2.1% nationally, homeownership registers in the top 5.3% nationally, and modeled transportation noise stands in the bottom 6.0% nationally. Poverty lands in the bottom 7.4% nationally. By contrast, unemployment is in the top 1.6% nationally, and modeled radon resides in the top 4.0% nationally. Walkability rests in the bottom 4.7% nationally, and slow internet speeds lies in the top 5.8% nationally. Lithium in drinking water sits in the top 6.8% nationally, and modeled fine-particle settles in the top 6.9% nationally.
In plain terms, 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. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. The nearest healthier ZIP overall is ZIP 57427, 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 1.94 years of 84.0, 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.
