Located in the state of Georgia in the United States, Atlanta is its capital and most populous city. It is the 38th most populated city in the United States, according to the 2020 census population estimate of 498,715. With such a population of more than 6 million people, it is the cultural and economic hub of the Atlanta metropolitan region, which is the ninth-largest metropolitan area in the United States. It serves as the county seat of Fulton County, which is Georgia's most populated county. Its location in the foothills of the Appalachian Mountains gives it a distinctive landscape that includes rolling hills and the densest urban tree coverage in the United States, among other attributes.
A huge state-sponsored railroad was the initial reason for the establishment of Atlanta. When the railroad saw rapid expansion, it quickly became a focal point for several railways, resulting in even more rapid development. As a result of its name being derived from the Western and Atlantic Railroad's local terminal, it has gained a reputation as a transit centre. The majority of it was destroyed during General William T. Sherman's March to the Sea, which took place during the conclusion of the American Civil War in November 1864. However, it recovered from the ashes and swiftly established itself as a national commercial hub and the unofficial capital of the "New South." During the 1950s and 1960s, it grew into a key organisational centre for the civil rights movement, with leaders like as Martin Luther King Jr., Ralph David Abernathy, and many more residents playing important roles in the movement's direction. Atlanta, Georgia has grown to become a worldwide transportation centre throughout the modern age, with Hartsfield–Jackson Atlanta International Airport serving as the world's busiest airport by passenger traffic since 1998.
Atlanta is the tenth biggest economy in the United States and the twentyth largest economy in the world, based on its gross domestic product (GDP). There are many main areas in the country's economy, the most prominent of which are aircraft, transportation, logistics, film and television production, media activities, professional and business services, medical services, and information technology. Initially fueled by the 1996 Summer Olympics, the gentrification of some of the city's areas has accelerated in the twenty-first century as a result of the expansion of the Atlanta Beltline. Because of this, the country's demography, political climate, aesthetics, and culture have all been transformed.
