Humphreys County, MS: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Humphreys County scores at the 22.5th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Humphreys County's flood-insurance compliance gap
Out of 381 homes FEMA counts inside Humphreys County's mapped flood zone, 59 carry the flood policy federal law requires there — 15.5% compliance, short of full coverage. Looking beyond the mandated zone, 3.1% of all residential structures in Humphreys County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.

Among the 3144 US counties FEMA scores for flood hazard, Humphreys County ranks 2479 — 1 being the highest hazard nationally — and 2647 by population among all 3144 counties covered here, where 1 is the largest.
