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.

Fiber broadband

100%

at the national maximum

Higher is healthier

ST99th
US99th
Definition & source ›

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

Full methodology ›

Grocery access

0.4 per 1,000 residents

in the top 2.3% nationally

Higher is healthier

ST98th
US98th
Definition & source ›

The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”

Arsenic in groundwater

1.2%

in the bottom 5.3% nationally

Lower is healthier

ST26th
US5th
Definition & 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.

Crowded housing

7.3%

in the top 8.0% nationally

Lower is healthier

ST96th
US92nd
Definition & source ›

The share of occupied homes with more than one person per room, the Census definition of crowded housing.

Humid extreme heat

The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

Reading across the data, the real pressures come first: crowded housing sits in the top 8.0% nationally, modeled humid heat lands in the top 9.6% nationally, and fatal road crashes lies in the top 10.1% nationally. Modeled loneliness stands in the top 13.3% nationally, and housing insecurity rests in the top 16% nationally. More encouragingly, fiber broadband registers at the national maximum, and grocery resides in the top 2.3% nationally. Modeled arsenic settles in the bottom 5.3% nationally, and housing-cost burden is in the bottom 16% nationally. Childcare sits in the top 16% nationally.

Defined simply, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. ZIP 30458, just across the boundary, comes out healthier overall.

Findings that name this ZIP

One of our published findings lists 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.

  • Clean environment, heavy chronic burden

    Where the environment and chronic illness point in opposite directions

    Environmental-hazard standing 91.5 (top 10%); chronic-disease standing 27.0 — 65 points apart, cleaner on the environment than it is on chronic illness.

    Ranked #1,421 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 1.34 years of 77.0, 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.
