The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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.

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.

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.

The number of civic and social organizations inside this ZIP’s boundary, per 1,000 residents.

Full methodology ›The read
In its overall standing, Rockville, South Carolina (ZIP 29487) lands in the top 13.5% healthiest ZIPs nationally (4,313th) and the top 7.7% of South Carolina (32nd).
Taken together, the data gives a genuinely mixed reading: modeled colon screening sits in the top 1.7% nationally, modeled cognitive disability lands in the bottom 8.4% nationally, and homeownership lies in the top 10.7% nationally. Modeled radon stands in the bottom 3.4% nationally. Modeled loud transportation noise rests at the national minimum, shared with about 22% of ZIPs. Crowded housing registers at the national minimum, shared with about 29% of ZIPs. On the other side, outer-floodplain exposure resides in the top 2.1% nationally, and floodplain exposure settles in the top 4.1% nationally. Fatal road crashes is in the top 10.7% nationally, and modeled humid heat sits in the top 11.2% nationally.
Against the wider neighborhood, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put simply, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". On the overall standing, ZIP 29455, just across the boundary, ranks healthier.

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 2.86 years of 77.4, 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. How distance is measured
