Displacement after Hurricane Katrina

People from the Gulf States region in the southern United States, most notably New Orleans, Louisiana, were forced to leave their homes because of the devastation brought on by Hurricane Katrina in 2005 and were unable to return because of a multitude of factors, and are collectively known as the Gulf Coast diaspora and by standard definition considered internally displaced persons. At their peak, hurricane evacuee shelters housed 273,000 people and, later, FEMA trailers housed at least 114,000 households.
