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.
Grocery access
0.25 per 1,000 residents
in the top 4.8% nationally
Higher is healthier
ST91stUS95thDefinition & 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.”

The number of physicians’ offices 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 ›Radon

Lower is healthier
ST32ndUS8thDefinition & 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 ›The read
By the composite measure, Dunn, North Carolina (ZIP 28334) sits in the bottom 36% nationally (20,579th) and the bottom 35% of North Carolina (516th).
The profile cuts both ways, and the readings bear that out: grocery registers in the top 4.8% nationally, subsidized affordable housing lands in the top 10.3% nationally, and physicians resides in the top 10.8% nationally. Distance to a community health center lies at the national minimum, shared with about 23% of ZIPs. Modeled radon settles in the bottom 7.9% nationally. Distance to a nursing home stands at the national minimum, shared with about 27% of ZIPs. Working the other way, fatal road crashes is in the top 11.8% nationally, and distance to an emergency room rests in the top 14.0% nationally. PFOA in drinking water sits in the top 14.2% nationally, and PFOS in drinking water registers in the top 14.9% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 27504, just across the boundary, ranks healthier overall.

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.
Below what income predicts
The ZIP codes that outlive their incomes
Estimated life expectancy is 75.6 ± 0.8 years. A median household income of $53,036 predicts 77.6 years — 2.0 years below.
Ranked #2,645 of the 5,842 ZIP codes this finding names, ordered by years above what income predicts, highest first.
Clean environment, heavy chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 83.3; chronic-disease standing 27.2 — 56 points apart, cleaner on the environment than it is on chronic illness.
Ranked #2,029 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

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 0.39 years of 75.6, 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.
