In more than two-thirds of the nation's 51 largest cities, the young, college-educated population in the past decade grew twice as fast within 3 miles of the urban center as in the rest of the metropolitan area — up an average 26% compared with 13% in other parts.

Even in Detroit, where the population shrank by 25% since 2000, downtown added 2,000 young and educated residents during that time, up 59% , according to analysis of Census data by Impresa Inc., an economic consulting firm.

"This is a real glimmer of hope," says Carol Coletta, head of CEOs for Cities, a non-profit consortium of city leaders that commissioned the research. "Clearly, the next generation of Americans is looking for different kinds of lifestyles — walkable, art, culture, entertainment."

Preference for urban living among young adults — especially the well-educated — has increased sharply, data show:

•In 2000, young adults with a four-year degree were about 61% more likely to live in close-in urban neighborhoods than their less-educated counterparts. Now, they are about 94% more likely.

•In five metropolitan areas — Boston, Chicago, New York, San Francisco, Washington — about two-thirds of young adults who live in the city center have at least a four-year college degree. Less than a third of the nation's 25- to 34-year-olds do.

"This is no longer anecdotal," Coletta says. "Every metro area has good suburbs, but if you don't have a strong downtown and close-in neighborhoods, then you're not offering a choice that many of them are seeking. Offering that choice is a real competitive advantage for cities."

Obviously, this is a topic that has been discussed to death but here is the quantitative side to the argument that some of us have made in the past.
