This was the lead story at HuffPo, this weekend, and it's an interesting one at that especially if your forte is marketing, demographics, and trend watching.
In a nutshell: The venerable Brookings Institution reports that scads of young, educated whites are flocking to the cities while more and more minorities are going suburban.
The study (which analyzed census data) confirms my hunch that the young often prefer urban because that's where the action is. That is, if your idea of action is a good-paying desk job, entertainment opportunities galore, dining out, and being around lots of other unattached twenty-year-olds with similar lifestyles.
Whereas those raising a family frequently prefer locales with safer schools, quieter streets, some green space, and a lower cost of living. According to the report, "the majority of the child population is now nonwhite." Apparently, more and more minorities want the time-honored benefits of suburbia for their own offspring.
Unfortunately the BI couldn't let the facts speak for themselves. They had to play the role of busybodies and make a pitch for more bureaucracy and more taxes, since their conclusions require money and are an encroachment of liberty.
From the article: "Among its recommendations: affordable housing and social services for older people in the suburbs; better transit systems to link cities and suburbs; and a new federal Office of New Americans to serve the education and citizenship needs of the rapidly growing immigrant community."
