The US Bureau of Census released the report Population Change in Central and Outlying Counties of Metropolitan Statistical Areas: 2000 to 2007, which shows that the U.S. continues to suburbanize. The new report compares population trends between "central counties" and "outlying counties".
"The nation's most remote suburbs – its exurbs – are growing much faster than the central counties. Whether this trend will now reverse, of course, is up to debate. Perhaps demographic changes and higher energy costs will slow expansion on the outer fringes. More likely, the current recession may well lead to less exurban growth, but history suggests this may prove only a short-lived trend."
