Radon
3.9 pCi/L
in the top 2.3% nationally
Lower is healthier
ST79thUS98thDefinition & 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 ›Fatal road crashes
0 per 100,000 residents per year
at the national minimum
Lower is healthier
ST1stUS1stDefinition & 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 ›Fiber broadband
99.8%
in the top 2.4% nationally
Higher is healthier
ST89thUS98thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Crowded housing
11.0%
in the top 3.9% nationally
Lower is healthier
ST90thUS96thDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.
Full methodology ›Distance to a Superfund site
91.4 mi
in the top 4.1% nationally
Higher is healthier
ST45thUS96thDefinition & 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 ›PFAS in drinking water
8.3%
in the bottom 5.3% nationally
Lower is healthier
ST5thUS5thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Walkability
1.8 intersections/sq mi
in the bottom 6.1% nationally
Higher is healthier
ST52ndUS6thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Distance to a community health center
20.9 mi
in the top 7.7% nationally
Lower is healthier
ST64thUS92ndDefinition & 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 ›Industrial-pollution burden
in the bottom 8.2% nationally
Lower is healthier
ST11thUS8thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Short sleep
29.6%
in the bottom 7.9% nationally
Lower is healthier
ST53rdUS8thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›The read
By the composite measure, Armour, South Dakota (ZIP 57313) sits in the bottom 44% nationally (18,009th) and the bottom 22% of South Dakota (282nd), based on limited data; treat as directional.
The main burdens in the data show plainly and lead the picture: modeled radon settles in the top 2.3% nationally, crowded housing stands in the top 3.9% nationally, and walkability is in the bottom 6.1% nationally. Distance to a community health center rests in the top 7.7% nationally. More positively, fatal road crashes sits at the national minimum, and fiber broadband registers in the top 2.4% nationally. Distance to a Superfund site lands in the top 4.1% nationally, and modeled pfas resides in the bottom 5.3% nationally. Distance to an emergency room lies at the national minimum, shared with about 11% of ZIPs. Modeled industrial-pollution burden settles in the bottom 8.2% nationally.
In plain language, 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. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. ZIP 57328, just across the boundary, ranks 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 0.95 years of 81.5, 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.
