Edgeless Cities: The Result Of Sprawl?

"Office space has been moving away from downtowns to suburban cities for decades, but a study out today shows that more jobs are creeping out even farther in a never-never land called 'edgeless cities.'More than one-third of office space in the 13 largest metropolitan areas is in low-rise buildings spread throughout semi-rural areas. These edgeless cities have no names because they're scattered across several municipalities. The office space is in low-rise buildings and warehouses that house shipping operations, phone centers, back offices of larger companies and medical laboratories."
