Atlanta is the capital and the most populous city of the state of Georgia, and the core city of the ninth most populous metropolitan area in the United States. It is the county seat of Fulton County, although portions of the city extend into DeKalb County. As of July 2006, the city of Atlanta had a population of 486,411 and a metropolitan population of 5,138,223. The July 2006 census estimate put the combined statistical area (CSA) population at 5,478,667. Residents of the city are known as Atlantans.
Atlanta has in recent years undergone a transition from a city of regional commerce to a city of international influence. Between 2000 and 2006, the Atlanta metropolitan area grew 20.5%, the highest percentage amongst the top-ten metro areas. Atlanta is often considered a poster child for cities worldwide experiencing rapid growth and urban sprawl.
During the Civil Rights Movement, Atlanta stood apart from southern cities that supported segregation, touting itself as "The City Too Busy to Hate." The city's progressive civil rights record and existing population of blacks, made it increasingly popular as a relocation destination for black Americans. Blacks soon became the dominant social and political force in the city, though today some measure of demographic diversification has taken place. Along with St. Louis and Los Angeles Atlanta is one of three cities in the United States to have hosted the Summer Olympic Games.
