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.

Distance to a Superfund site

223.5 mi

in the top 0.8% nationally

Higher is healthier

ST75th
US99th
Definition & 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 ›

Homeownership rate

100%

at the national maximum

Higher is healthier

ST99th

Definition & source ›

The share of occupied homes that are owned, rather than rented, by the people living in them.

Distance to a nursing home

20.5 mi

Lower is healthier

ST92nd

Definition & source ›

The distance in miles from this ZIP’s edge to the nearest Medicare- or Medicaid-certified nursing home.

Full methodology ›

Floodplain exposure

0.00%

at the national minimum

Lower is healthier

ST1st
US1st
Definition & source ›

The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.

Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

Full methodology ›

Lithium in drinking water

88 µg/L

in the top 3.4% nationally

Lower is healthier

ST73rd
US97th
Definition & source ›

The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.

Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Full methodology ›

Slow internet speeds

2.5%

in the top 4.7% nationally

Lower is healthier

ST75th
US95th
Definition & source ›

The share of homes whose fastest available download speed is under 10 Mbps.

Full methodology ›

Radon

3.2 pCi/L

in the top 8.2% nationally

Lower is healthier

ST39th
US92nd
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 ›

Energy-cost burden

5.5%

in the top 5.2% nationally

Lower is healthier

ST95th
US95th
Definition & source ›

The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.

A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.

Full methodology ›

Natural-disaster risk

in the bottom 6.9% nationally

Lower is healthier

ST4th
US7th
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 ›

Humid extreme heat

10 days/year

in the bottom 7.0% nationally

Lower is healthier

ST17th
US7th
Definition & 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.

Plainly stated, a few measures mark out this area: distance to a nursing home resides in the top 3.2% nationally, and lithium in drinking water lands in the top 3.4% nationally. Slow internet speeds registers in the top 4.7% nationally, and modeled radon sits in the top 8.2% nationally. Modeled energy burden rests in the top 5.2% nationally. Better still, distance to a Superfund site is in the top 0.8% nationally, homeownership stands at the national maximum, and floodplain exposure settles at the national minimum. Modeled disaster risk lies in the bottom 6.9% nationally, and humid heat resides in the bottom 7.0% nationally.

In plainer terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. For a healthier nearby ZIP overall, look to ZIP 58368, just across the boundary.

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 1.28 years of 76.8, 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.
