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.
Child-care access
2.1 per 1,000 residents
in the top 0.3% nationally
Higher is healthier
ST98thUS99thDefinition & 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 ›Elder-services access

in the top 0.7% nationally
Higher is healthier
ST90thUS99thDefinition & 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.

ST79thUS99thDefinition & 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 ›Fine-particle (PM2.5) exceedance

in the top 1.9% nationally
Lower is healthier
ST93rdUS98thDefinition & 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 ›Radon
3.3 pCi/L
in the top 7.0% nationally
Lower is healthier
ST55thUS93rdDefinition & 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 ›Fiber broadband
98.7%
in the top 5.4% nationally
Higher is healthier
ST66thUS95thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Fatal road crashes

in the top 8.0% nationally
Lower is healthier
ST88thUS92ndDefinition & 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 ›Recreation access
1 per 1,000 residents
in the top 8.1% nationally
Higher is healthier
ST76thUS92ndDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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 ›The read
Underwood, North Dakota (ZIP 58576), by its composite score, sits in the top 23% healthiest ZIPs nationally (7,306th) and the top 26% of North Dakota (96th).
The data opens on a genuinely even set of readings: childcare is in the top 0.3% nationally, and elder services lands in the top 0.7% nationally. Distance to a Superfund site stands in the top 0.7% nationally, and pharmacy registers in the top 0.9% nationally. Fiber broadband settles in the top 5.4% nationally, and recreation sits in the top 8.1% nationally. On the other side, modeled fine-particle lies in the top 1.9% nationally, modeled radon rests in the top 7.0% nationally, and fatal road crashes resides in the top 8.0% nationally. Slow internet speeds is in the top 8.6% nationally.
Next to the surrounding area, childcare runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. For a healthier comparison close by, see ZIP 58735, about 15 miles away.

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 1.44 years of 79.7, 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
