JULY 29, 2015 — Hurricane Katrina is the costliest U.S. hurricane on record, and the deadliest to strike our nation since 1928. After initially making U.S. landfall on Aug. 25, 2005, in South Florida as a Category 1, it moved into the Gulf of Mexico, rapidly intensified into a Category 5 and made its second landfall early the morning of Aug. 29 in Plaquemines Parish in Southeast Louisiana as a strong Category 3 with sustained winds of 125 mph. After briefly moving over water, it made a third landfall later that morning near the Louisiana-Mississippi border. Katrina  weakened as it moved north-northeastward over land but remained a hurricane as far inland as the vicinity of Meridian, Miss., a straight distance of more than 130 miles from the coast. Ultimately, Katrina was responsible for 1,833 deaths and damage estimated at $151 billion, including $75 billion in the New Orleans area and along the Mississippi coast. Federal disaster declarations issued in the hurricane’s wake covered not only all of the coastal counties of Louisiana, Mississippi and Alabama, but extended well inland to include cities such as Baton Rouge, La.; Jackson, Miss.; and Tuscaloosa, Ala.

This edition of Facts for Features focuses on the two areas that received significant damage: the New Orleans metro area and coastal portions of Mississippi. It compares statistics from before the hurricane struck to a year later, and currently, using a variety of demographic and economic measures. One may use the sources listed below to look at change over the period in other counties and parishes affected by the storm. It should be noted that 2005 was the most active hurricane season ever recorded, with three other major hurricanes also striking the U.S.: Dennis, Rita and Wilma.
