Outer-floodplain exposure
20.7%
in the top 1.9% nationally
Lower is healthier
ST99thUS98thDefinition & 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.
Full methodology ›PFAS in drinking water
7.0%
in the bottom 3.4% nationally
Lower is healthier
ST6thUS3rdDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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.

Lower is healthier
ST97thUS97thDefinition & 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 ›Loneliness

The estimated share of adults who report feeling lonely.
Full methodology ›Humid extreme heat
149.1 days/year
in the top 5.0% nationally
Lower is healthier
ST95thUS95thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Radon
0.8 pCi/L
in the bottom 9.0% nationally
Lower is healthier
ST4thUS9thDefinition & 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.

Combined exposures in this ZIP
More than one environmental exposure stands out in this ZIP. Each is established independently and shown on its own above; they are grouped here for context — not because one causes the other.
This area ranks among the highest 10% of US ZIP codes for both humid-heat days and flood exposure.

The read
Ludowici, Georgia (ZIP 31316), by its overall standing, sits in the bottom 31% nationally (22,058th) and the bottom 43% of Georgia (406th).
The data is direct about where this area carries real strain: outer-floodplain exposure is in the top 1.9% nationally, floodplain exposure resides in the top 3.5% nationally, and modeled loneliness rests in the top 3.8% nationally. Modeled humid heat lies in the top 5.0% nationally, slow internet speeds sits in the top 10.7% nationally, and modeled short sleep settles in the top 12.3% nationally. More encouragingly, modeled pfas registers in the bottom 3.4% nationally. Distance to a community health center stands at the national minimum, shared with about 23% of ZIPs. Modeled arsenic lands in the bottom 11.6% nationally, and radon is in the bottom 9.0% nationally.
Held up against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. The nearest ZIP ranking healthier overall is ZIP 31301, 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

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 0.82 years of 76.2, 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. How distance is measured
