For well over a decade urban boosters have heralded the shift among young Americans from suburban living and toward dense cities. As one Wall Street Journal report suggests, young people will abandon their parents’ McMansions for urban settings, bringing about the high-density city revival so fervently prayed for by urban developers, architects and planners.
Some demographers claim that “white flight” from the city is declining, replaced by a “bright flight” to the urban core from the suburbs. “Suburbs lose young whites to cities,” crowed one Associated Press headline last year.
Yet evidence from the last Census show the opposite: a marked acceleration of movement not into cities but toward suburban and exurban locations. The simple, usually inexorable effects of maturation may be one reason for this surprising result. Simply put, when 20-somethings get older, they do things like marry, start businesses, settle down and maybe start having kids.
