Radon
3.5 pCi/L
in the top 4.6% nationally
Lower is healthier
ST55thUS95thDefinition & 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 ›Loneliness
27.4%
in the bottom 4.5% nationally
Lower is healthier
ST23rdUS4thDefinition & source ›
The estimated share of adults who report feeling lonely.
Full methodology ›Fiber broadband
98.9%
in the top 5.0% nationally
Higher is healthier
ST66thUS95thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Short sleep
28.7%
in the bottom 4.9% nationally
Lower is healthier
ST30thUS5thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Child-care access
0.66 per 1,000 residents
in the top 5.9% nationally
Higher is healthier
ST81stUS94thDefinition & 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 ›Housing insecurity
6.9%
in the bottom 6.7% nationally
Lower is healthier
ST8thUS7thDefinition & source ›
The estimated share of adults who experienced housing insecurity in the past 12 months.
Full methodology ›Nitrate in drinking water
0.34%
in the top 7.6% nationally
Lower is healthier
ST97thUS92ndDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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
ST72ndUS91stDefinition & 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 ›Walkability
2.3 intersections/sq mi
in the bottom 9.3% nationally
Higher is healthier
ST63rdUS9thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Utility shut-off threat
4.7%
in the bottom 9.7% nationally
Lower is healthier
ST8thUS10thDefinition & source ›
The estimated share of adults whose household was threatened with a utility shut-off in the past 12 months.
Full methodology ›The read
By its overall health score, Garretson, South Dakota (ZIP 57030) lands in the top 21% healthiest ZIPs nationally (6,665th) and the top 14.8% of South Dakota (53rd), based on limited data; treat as directional.
Neither strongly one way nor the other, the measures sit mixed: modeled loneliness lies in the bottom 4.5% nationally, and fiber broadband resides in the top 5.0% nationally. Modeled short sleep lands in the bottom 4.9% nationally, and childcare registers in the top 5.9% nationally. Modeled housing insecurity sits in the bottom 6.7% nationally, and utility shutoff rests in the bottom 9.7% nationally. Against that, modeled radon is in the top 4.6% nationally, nitrate stands in the top 7.6% nationally, and fine-particle settles in the top 8.6% nationally. Walkability lies in the bottom 9.3% nationally.
To translate a couple of terms, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Nitrate is a groundwater compound from fertilizer, manure, and sewage, 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. Overall, the nearest healthier neighbor is ZIP 57005, 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 1.01 years of 80.2, 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
