The capital is Baton Rouge. By the early 21st century southern Louisiana contained nearly three-fourths of the state’s population. A predominantly urban population was achieved for the first time in 1950. Since then the vast majority of Louisianans have been urban dwellers, mostly in the Greater New Orleans area and Baton Rouge, the seat of state government and the centre of the chemical industry. Other urban concentrations are located in Lafayette in the south-central part of the state and at Shreveport in the northwest. Much of northern and western Louisiana is sparsely populated.
