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

4.2 pCi/L

in the top 1.3% nationally

Lower is healthier

ST93rd
US99th
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 ›

Natural-disaster risk

in the top 0.8% nationally

Lower is healthier

ST99th
US99th
Definition & source ›

This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.

Full methodology ›

Expected annual disaster loss

$1

in the top 1.3% nationally

Lower is healthier

ST99th
US99th
Definition & source ›

FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.

ST66th
US97th
Definition & source ›

31 mi

in the top 3.9% nationally

Lower is healthier

ST82nd

Lower is healthier

ST82nd
US93rd
Definition & source ›

in the top 14.3% nationally

Lower is healthier

ST97th
US86th
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.

Strengths and concerns sit side by side across the measures here: distance to a Superfund site is in the top 2.8% nationally. Distance to an emergency room stands at the national minimum, shared with about 11% of ZIPs. Subsidized affordable housing settles in the top 8.1% nationally, modeled mammography lies in the top 5.5% nationally, and modeled short sleep resides in the bottom 11.0% nationally. On the other hand, modeled radon lands in the top 1.3% nationally, disaster risk registers in the top 0.8% nationally, and expected annual loss sits in the top 1.3% nationally. Distance to a community health center rests in the top 3.9% nationally, and modeled fine-particle is in the top 7.3% nationally.

Compared with the ZIPs it borders, expected annual loss runs far higher than the surrounding ZIPs on this measure. In plainer terms, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. For a healthier nearby ZIP overall, look to ZIP 57223, just across the boundary.

Findings that name this ZIP

2 of our published findings list this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.

  • Above what income predicts

    The ZIP codes that outlive their incomes

    Estimated life expectancy is 82.1 ± 1.8 years. A median household income of $72,878 predicts 78.8 years — 3.2 years above.

    Ranked #371 of the 5,842 ZIP codes this finding names, ordered by years above what income predicts, highest first.

  • Heavy environment, light chronic burden

    Where the environment and chronic illness point in opposite directions

    Environmental-hazard standing 14.8; chronic-disease standing 65.1 — 50 points apart, heavier on the environment than it is on chronic illness.

    Ranked #14,414 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

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 0.91 years of 82.1, 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.
