Carter County, MO: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Carter County scores at the 60.6th 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 1.9 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
FEMA hasn't published a residential structure count for Carter 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, 1.2% of all residential structures in Carter County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Carter County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Carter County ranks 1298 — 1 being the highest hazard nationally — and 2791 by population among all 3144 counties covered here, where 1 is the largest. Carter County, Missouri is home to about 5,359 people across 507.359 square miles of land.
