About this state

FEMA disaster context for Louisiana

Louisiana has 2,640 county-level FEMA disaster declarations spread across 64 counties. The most common declaration type is hurricane. Across all counties, FEMA datasets track $34.8B in combined public and individual assistance obligations.

The counties with the heaviest disaster history are Ascension Parish (58 declarations), St. Martin Parish (54), and Lafourche Parish (53). Each county page breaks down the timeline, hazard mix, spending categories, and flood insurance signals for that specific area.

Declaration counts reflect how often FEMA formally declared a disaster or emergency affecting a county — not the total number of natural events. A single hurricane can generate declarations across dozens of counties and multiple states. The county pages linked above show the per-county detail behind these state-level totals.
