Jackson Parish, LA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Jackson Parish scores at the 27.6th 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 2 years. 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
Out of 56 homes FEMA counts inside Jackson Parish's mapped flood zone, 18 carry the flood policy federal law requires there — 32.1% compliance, short of full coverage. Looking beyond the mandated zone, 0.4% of all residential structures in Jackson Parish carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Jackson Parish compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Jackson Parish ranks 2325 — 1 being the highest hazard nationally — and 2102 by population among all 3144 counties covered here, where 1 is the largest. About 14,797 people live in Jackson Parish, Louisiana, spread over 569.655 square miles.
