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.

The read
Callahan, Florida (ZIP 32011), in overall standing, comes out in the bottom 38% nationally (19,802nd) and the bottom 30% of Florida (678th).
An even profile, with readings pulling both ways: modeled arsenic rests in the bottom 14.8% nationally, modeled radon settles in the bottom 17% nationally, and subsidized affordable housing lands in the top 18% nationally. Homeownership rests in the top 25% nationally, and distance to a hazardous-chemical facility settles in the top 25% nationally. Against that, modeled humid heat lands in the top 2.6% nationally, and floodplain exposure rests in the top 7.2% nationally. Distance to an emergency room settles in the top 21% nationally, and modeled pfas lands in the top 22% nationally. Fatal road crashes rests in the top 23% nationally.
Set within its surrounding area, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, for reference, 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. 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. The closest healthier ZIP overall is ZIP 32009, 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 0.65 years of 76.9, 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.
