What that means for the future remains uncertain, but a closer look provides some clues.
According to a blog by Chris Cilliza in the Washington Post, politically the United States is already seeing a racial and generational divide that could get even wider.
Cilliza points to an essay by Paul Taylor of the Poynter Institute entitled Next America.
Taylor mentions that in the 2012 presidential election, President Obama won the under 30 vote by a 60 percent to 37 percent margin.
He lost the 65 and older vote by 12 points. The 35 point swing is particularly noteworthy when you compare that to the 2000 election where there was no generational gap.
Taylor also wonders whether racial categories will make much sense in 2050 with so many more people marrying across racial categories. 15.5 percent now versus 2 percent in 1960.
