Most disaster-prone counties in Louisiana

Louisiana has 2,640 county-level FEMA disaster declarations across 64 counties. The dominant hazard type is hurricane. Ascension Parish leads with 58 declarations, followed by St. Martin Parish and Lafourche Parish.

This ranking shows every county in Louisiana ordered by how many times FEMA has issued a disaster declaration affecting it. Counties near coastlines, river systems, or wildfire corridors tend to appear at the top because the same geographic exposure produces recurring events across decades.

Each county links to a full disaster history page with the complete declaration timeline, hazard type breakdown, decade trends, and whatever FEMA spending data is available. For a national view, see the most disaster-prone counties in America page.
