Baton Rouge is the capital of the U.S. state of Louisiana and its second-largest city. The seat of East Baton Rouge Parish, the city is located on the eastern bank of the Mississippi River. As the "Capital City", Baton Rouge is the political hub for Louisiana, and is the second-largest metropolitan city in the state, with a growing population of 229,426 people as of 2013. The metropolitan area surrounding the city, known as Greater Baton Rouge, has a population of 820,159 people as of 2013. The urban area has around 594,309 inhabitants.
In the 1950s and 1960s, Baton Rouge experienced a boom in the petrochemical industry, causing the city to expand away from the original center. In recent years, government and business have begun a move back to the central district. A building boom that began in the 1990s continues today, with multimillion-dollar projects for quality of life improvements and new construction happening all over the city. In the 2000s (decade), Baton Rouge has proven to be one of the fastest-growing cities in the South in terms of technology. Baton Rouge's population temporarily exploded after Hurricane Katrina, as it accepted as many as 200,000 displaced residents. Metropolitan Baton Rouge is one of the fastest growing metropolitan areas in the U.S. (under 1 million), with 602,894 in 2000 and 802,484 people as of the 2010 census. The city has a mix of the cultures found throughout Louisiana, from which it developed its motto: "Authentic Louisiana at every turn".
