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.
Walkability
0.9 intersections/sq mi
in the bottom 2.3% nationally
Higher is healthier
ST20thUS2ndDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Fatal road crashes
53.7 per 100,000 residents per year
in the top 3.2% nationally
Lower is healthier
ST93rdUS97thDefinition & 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 ›Elder-services access
0.4 per 1,000 residents
in the top 3.2% nationally
Higher is healthier
ST87thUS97thDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Radon
3.1 pCi/L
in the top 8.3% nationally
Lower is healthier
ST33rdUS92ndDefinition & 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 ›Air-toxics cancer risk
18.7 per million
in the bottom 7.0% nationally
Lower is healthier
ST21stUS7thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›Nitrate in drinking water
0.14%
in the top 8.1% nationally
Lower is healthier
ST96thUS92ndDefinition & 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 ›Humid extreme heat
15.5 days/year
in the bottom 12.1% nationally
Lower is healthier
ST7thUS12thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Housing-cost burden
36.3%
in the top 15% nationally
Lower is healthier
ST94thUS85thDefinition & source ›
The share of households spending 30% or more of their income on housing.
Full methodology ›Median household income
$106,250
in the top 15% nationally
Higher is healthier
ST92ndUS85thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Loud transportation noise
0.61%
in the top 32% nationally
Lower is healthier
ST95thUS68thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.
Full methodology ›The read
Hermosa, South Dakota (ZIP 57744), on the composite measure, lands in the top 35% healthiest ZIPs nationally (11,241st) and the top 46% of South Dakota (167th), based on limited data; treat as directional.
The profile cuts both ways, and the readings bear that out: elder services lands in the top 3.2% nationally, modeled air-toxics cancer risk resides in the bottom 7.0% nationally, and modeled short sleep lies in the bottom 10.5% nationally. Outpatient settles in the top 11.5% nationally, and modeled humid heat stands in the bottom 12.1% nationally. Working the other way, walkability is in the bottom 2.3% nationally, and fatal road crashes rests in the top 3.2% nationally. Modeled radon sits in the top 8.3% nationally, and nitrate registers in the top 8.1% nationally. Modeled fine-particle lands in the top 13.5% nationally.
Set against the neighboring ZIPs, park land runs far higher than the surrounding ZIPs on this measure. In everyday language, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. A healthier neighbor overall sits at ZIP 57702, 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 0.82 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.
