Downtown Atlanta is the central business district of Atlanta, Georgia, United States. The larger of the city's two other commercial districts (Midtown and Buckhead), it is the location of many corporate and regional headquarters; city, county, state, and federal government facilities; Georgia State University; sporting venues; and most of Atlanta's tourist attractions. It measures approximately four square miles, and had 26,700 residents as of 2010. Similar to other central business districts in the United States, it has recently undergone a transformation that includes the construction of new condos and lofts, renovation of historic buildings, and arrival of new residents and businesses.
