ZIP codes at the highest natural hazard risk — the whole United States

ZIP codes with fewer than 1,000 residents are excluded: a median drawn from a handful of households carries a margin of error wider than the differences being ranked. Figures the Census suppressed as unreliable are excluded too, so a ZIP code missing here has no published value rather than a low one.
