Demographically, Republicans remain overwhelmingly white and their average age now approaches 50. Fully 87% of Republicans are non-Hispanic whites, a figure which has changed little since 2000.
Meanwhile, the percentage of Democrats who say their political views are liberal has risen from 28% in 2000 to 34% in 2008 and 38% in 2012 surveys by the Pew Research Center. For the first time, there are as many liberal Democrats as moderate Democrats.
In contrast to Republicans, Democrats have grown increasingly diverse. A narrow majority of Democrats (55%) are non-Hispanic whites, down from 64% in 2000. As in recent years, most Democrats are women (59%). And while the average age of self-described Democrats has risen since 2008 – from 46.9 to 47.7 – Democrats continue to be younger than Republicans on average (47.7 vs. 49.7).
