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.
Floodplain exposure
30.4%
in the top 9.9% nationally
Lower is healthier
ST87thUS90thDefinition & 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 ›Radon
0.7 pCi/L
in the bottom 3.6% nationally
Lower is healthier
ST14thUS4thDefinition & 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
1.8%
in the bottom 9.1% nationally
Lower is healthier
ST11thUS9thDefinition & 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.

The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.

Full methodology ›The read
By the composite measure, Winnabow, North Carolina (ZIP 28479) sits in the top 13.2% healthiest ZIPs nationally (4,229th) and the top 10.4% of North Carolina (82nd).
Where this area does well, the measures make it plain: modeled radon rests in the bottom 3.6% nationally, energy burden sits in the bottom 9.1% nationally, and colon screening registers in the top 8.9% nationally. Modeled mammography lands in the top 10.6% nationally. Distance to a nursing home resides at the national minimum, shared with about 27% of ZIPs. Modeled food insecurity lies in the bottom 14.1% nationally, and fair or poor health settles in the bottom 12.7% nationally. Against that, floodplain exposure stands in the top 9.9% nationally, and distance to a Superfund site is in the bottom 14.2% nationally. Outer-floodplain exposure rests in the top 14.9% nationally.
Compared with the ZIPs that surround it, park land runs far lower 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". ZIP 28449, just across the boundary, ranks healthier overall.

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 1.08 years of 79.2, 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.
