The gentrification of Atlanta has been the source of both praise and condemnation.
 Gentrification of Atlanta's inner-city neighborhoods began in the 1970s, and it has continued, at varying levels of intensity, into the present.
 Many factors have contributed to the city's gentrification.
 A major increase in gentrification that occurred in the last years of the twentieth century has been attributed to the 1996 Summer Olympics.
 However, during the 2000s, Atlanta underwent a profound transformation demographically, physically, and culturally.
 Suburbanization, rising prices, a booming economy, and new migrants decreased the city’s black percentage from a high of 67% in 1990 to 54% in 2010.
 From 2000 to 2010, Atlanta gained 22,763 white residents, 5,142 Asian residents, and 3,095 Hispanic residents, while the city’s black population decreased by 31,678.
 Much of the city’s demographic change during the decade was driven by young, college-educated professionals: from 2000 to 2009, the three-mile radius surrounding Downtown Atlanta gained 9,722 residents aged 25 to 34 holding at least a four-year degree, an increase of 61%.
 Between the mid-1990s and 2010, stimulated by funding from the HOPE VI program, Atlanta demolished nearly all of its public housing, a total of 17,000 units and about 10% of all housing units in the city.
 In 2005, the $2.8 billion BeltLine project was adopted, with the stated goals of converting a disused 22-mile freight railroad loop that surrounds the central city into an art-filled multi-use trail and increasing the city’s park space by 40%.
 Lastly, Atlanta’s cultural offerings expanded during the 2000s: the High Museum of Art doubled in size; the Alliance Theatre won a Tony Award; and numerous art galleries were established on the once-industrial Westside.
