Louisiana is a state located in the southern region of the United States. Louisiana is the 31st most extensive and the 25th most populous of the 50 United States. Its capital is Baton Rouge and largest city is New Orleans. Louisiana is the only state in the U.S. with political subdivisions termed parishes, which are local governments equivalent to counties. The largest parish by population is East Baton Rouge Parish, and the largest by land area is Cameron Parish.
August 29, 2005, Hurricane Katrina (Category 3 at landfall) struck and devastated southeastern Louisiana, where it breached and undermined levees in New Orleans, causing 80% of the city to flood. Most people had been evacuated, but the majority of the population became homeless. The city was virtually closed until October. It is estimated that more than two million people in the Gulf region were displaced by the hurricane, and that more than 1,500 fatalities resulted in Louisiana alone.
