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.

Nitrate in drinking water

71.5%

in the top 0.4% nationally

Lower is healthier

ST99th
US99th
Definition & 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 ›

Radon

3.7 pCi/L

in the top 3.8% nationally

Lower is healthier

ST88th
US96th
Definition & 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 ›

Walkability

1.4 intersections/sq mi

in the bottom 4.1% nationally

Higher is healthier

ST2nd
US4th
Definition & source ›

The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

Full methodology ›

PFAS in drinking water

7.6%

in the bottom 4.3% nationally

Lower is healthier

ST2nd
US4th
Definition & 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 ›

Fiber broadband

98.9%

in the top 5.1% nationally

Higher is healthier

ST86th
US95th
Definition & source ›

The share of homes where fiber-optic internet service is available.

Full methodology ›

Poverty rate

2.3%

in the bottom 7.5% nationally

Lower is healthier

ST9th
US7th
Definition & source ›

The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.

Full methodology ›

Short sleep

30.5%

in the bottom 12.0% nationally

Lower is healthier

ST5th
US12th
Definition & source ›

The estimated share of adults who usually sleep less than seven hours in a 24-hour period.

Full methodology ›

Air-toxics cancer risk

20 per million

in the bottom 25% nationally

Lower is healthier

ST1st
US25th
Definition & 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.

The read

Overall, Grinnell, Kansas (ZIP 67738) lands in the top 41% healthiest ZIPs nationally (13,220th) and the top 29% of Kansas (197th), based on limited data; treat as directional.

The signals balance out across the profile, strengths against concerns: modeled pfas is in the bottom 4.3% nationally, and fiber broadband settles in the top 5.1% nationally. Unemployment resides at the national minimum, shared with about 15% of ZIPs. Poverty registers in the bottom 7.5% nationally. Households without a vehicle rests at the national minimum, shared with about 16% of ZIPs. Set against that, modeled nitrate stands in the top 0.4% nationally, modeled radon lies in the top 3.8% nationally, and walkability lands in the bottom 4.1% nationally. Modeled extreme heat sits in the top 10.7% nationally, and tree cover is in the bottom 10.9% nationally.

A note on the terms: nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. 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. For a healthier nearby comparison, ZIP 67740, just across the boundary, ranks better overall.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.50 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.
