If you want to know the demographic changes that worked to President Bush’s advantage in the election, look no further:

In this month’s election, President Bush carried 97 of the nation’s 100 fastest-growing counties, most of them “exurban” communities that are rapidly transforming farmland into subdivisions and shopping malls on the periphery of major metropolitan areas.

Together, these fast-growing communities provided Bush a punishing 1.72 million vote advantage over Democrat John F. Kerry, according to a Times analysis of election results. That was almost half the president’s total margin of victory.
