Loneliness

ST1stUS1stDefinition & source ›
The estimated share of adults who report feeling lonely.

ST99thUS99thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Floodplain exposure
57.2%
in the top 2.9% nationally
Lower is healthier
ST94thUS97thDefinition & 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 ›Outer-floodplain exposure

Lower is healthier
ST96thUS97thDefinition & source ›
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 estimated share of adults who usually sleep less than seven hours in a 24-hour period.

Higher is healthier
ST97thUS96thDefinition & source ›
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 ›Lithium in drinking water
9.9 µg/L
in the bottom 6.2% nationally
Lower is healthier
ST2ndUS6thDefinition & 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 ›Recreation access

in the top 6.3% nationally
Higher is healthier
ST98thUS94thDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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.

The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
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 ›The read
ZIP 29926, one of several in Hilton Head Island, South Carolina ranks in the top 12.0% healthiest ZIPs nationally (3,842nd) and the top 7.0% of South Carolina (29th).
A profile of give and take, with clear readings each way: modeled loneliness registers in the bottom 0.2% nationally, and short sleep lies in the bottom 2.4% nationally. Physicians is in the top 4.1% nationally. Distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. Lithium in drinking water lies in the bottom 6.2% nationally, and recreation is in the top 6.3% nationally. On the other side, modeled disaster risk registers in the top 0.6% nationally, floodplain exposure lies in the top 2.9% nationally, and outer-floodplain exposure is in the top 3.4% nationally. PFOA in drinking water registers in the top 6.5% nationally.
Against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For context, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. The closest ZIP that ranks healthier overall is ZIP 29909, just across the boundary.

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

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
