Dunklin County, MO: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Dunklin County scores at the 42.7th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. 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 1.3 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
FEMA hasn't published a residential structure count for Dunklin County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 1.9% of all residential structures in Dunklin County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Dunklin County ranks
Among the 3144 US counties FEMA scores for flood hazard, Dunklin County ranks 1863 — 1 being the highest hazard nationally — and 1543 by population among all 3144 counties covered here, where 1 is the largest. Dunklin County, Missouri is home to about 27,002 people across 541.909 square miles of land.

Where Dunklin County's figures come from
