Hurricane Katrina displaced over one million Louisiana residents -- an estimated 277,000 did not come back to resettle.
Threatened by one of the most destructive and influential storms in United States history, those living in the path of Hurricane Katrina fled to every state in the country, with many unable to return home to Louisiana after the storm left. This map, which uses data from the 2006 American Community Survey, presents a good, but imperfect illustration of where evacuees ended up by showing where residents who lived in Louisiana in 2005 moved to as of 2006.
