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.

Binge drinking

21.1%

in the top 3.1% nationally

Lower is healthier

ST82nd
US97th
Definition & source ›

The estimated share of adults who report binge drinking — five or more drinks on one occasion for men, four or more for women.

Full methodology ›

Lithium in drinking water

84 µg/L

in the top 4.3% nationally

Lower is healthier

ST80th
US96th
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 ›

Pharmacy access

0.39 per 1,000 residents

in the top 8.6% nationally

Higher is healthier

ST89th
US91st
Definition & source ›

The number of pharmacies located 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 ›

Tooth loss

6.6%

in the bottom 6.7% nationally

Lower is healthier

ST4th
US7th
Definition & source ›

The estimated share of adults aged 65 and older who have lost all of their natural teeth.

Full methodology ›

Outpatient-care access

0.39 per 1,000 residents

in the top 12.0% nationally

Higher is healthier

ST90th
US88th
Definition & source ›

The number of outpatient clinics located 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 ›

Distance to a Superfund site

3.1 mi

in the bottom 15.0% nationally

Higher is healthier

ST5th
US15th
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 ›

66 units

in the top 22% nationally

Higher is healthier

Full methodology ›

Air-toxics cancer risk

20 per million

in the bottom 25% nationally

Lower is healthier

ST1st

The clearest bright points in the data come first here: distance to an emergency room lands at the national minimum, shared with about 11% of ZIPs. Pharmacy stands in the top 8.6% nationally, and modeled tooth loss registers in the bottom 6.7% nationally. Outpatient settles in the top 12.0% nationally, poverty sits in the bottom 13.0% nationally, and modeled housing insecurity lies in the bottom 13.3% nationally. Distance to a nursing home rests at the national minimum, shared with about 27% of ZIPs. By contrast, modeled binge drinking resides in the top 3.1% nationally, lithium in drinking water is in the top 4.3% nationally, and modeled radon lands in the top 16% nationally.

For anyone unfamiliar, 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 comparison close by, see ZIP 52756, 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 0.75 years of 79.8, 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.
