Emptying Suburbs Sign of Things to Come

"While the foreclosure epidemic has left communities across the United States overrun with unoccupied houses and overgrown grass, underneath the chaos another trend is quietly emerging that, over the next several decades, could change the face of suburban American life as we know it.

This trend, according to Christopher Leinberger, an urban planning professor at the University of Michigan and visiting fellow at the Brookings Institution, stems not only from changing demographics but also from a major shift in the way an increasing number of Americans -- especially younger generations -- want to live and work.

"The American dream is absolutely changing," he told CNN.

This change can be witnessed in places like Atlanta, Georgia, Detroit, Michigan, and Dallas, Texas, said Leinberger, where once rundown downtowns are being revitalized by well-educated, young professionals who have no desire to live in a detached single family home typical of a suburbia where life is often centered around long commutes and cars.

Instead, they are looking for what Leinberger calls "walkable urbanism" -- both small communities and big cities characterized by efficient mass transit systems and high density developments enabling residents to walk virtually everywhere for everything -- from home to work to restaurants to movie theaters."
