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.
Radon
4.6 pCi/L
in the top 0.7% nationally
Lower is healthier
ST89thUS99thDefinition & 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 ›Arsenic in groundwater
39.8%
in the top 1.6% nationally
Lower is healthier
ST98thUS98thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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 ›Transportation noise
0.00%
in the bottom 5.0% nationally
Lower is healthier
ST5thUS5thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.

The share of households with a broadband internet subscription.
Full methodology ›Walkability
1.7 intersections/sq mi
in the bottom 5.8% nationally
Higher is healthier
ST1stUS6thDefinition & 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 nursing home

Lower is healthier
ST98thUS86thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Medicare- or Medicaid-certified nursing home.
Full methodology ›High cholesterol

The estimated share of adults who have been told by a health professional that they have coronary heart disease or angina.
Full methodology ›Air-toxics cancer risk

Combined exposures in this ZIP
More than one environmental exposure stands out in this ZIP. Each is established independently and shown on its own above; they are grouped here for context — not because one causes the other.
USGS models a high likelihood that groundwater arsenic here exceeds 10 µg/L — the level EPA sets as the limit for public water systems — and this area's modeled radon runs above EPA's 4 pCi/L action level.

The read
Linn Grove, Iowa (ZIP 51033) ranks in the top 47% healthiest ZIPs nationally (15,168th) and the bottom 36% of Iowa (593rd).
A profile of give and take, with clear readings each way: modeled transportation noise is in the bottom 5.0% nationally. Households without a vehicle registers at the national minimum, shared with about 16% of ZIPs. Modeled loud transportation noise lies at the national minimum, shared with about 22% of ZIPs. Modeled short sleep is in the bottom 14.0% nationally. On the other side, modeled radon registers in the top 0.7% nationally, modeled arsenic lies in the top 1.6% nationally, and home broadband subscription is in the bottom 5.7% nationally. Walkability registers in the bottom 5.8% nationally, modeled fine-particle lies in the top 11.7% nationally, and distance to a nursing home is in the top 13.6% nationally.
For context, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Arsenic is a natural groundwater contaminant, 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. The closest ZIP that ranks healthier overall is ZIP 50576, 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 1.14 years of 80.5, 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.
