Democrats Continue to Outnumber Republicans

The political affiliations of the American public have not changed much in decades. According to the 2021 General Social Survey, 44 percent of people aged 18 or older identify themselves as Democrats, 30 percent as Republicans, and 23 percent as independents. Here's the GSS question: "Generally speaking, do you usually think of yourself as a Republican, Democrat, Independent, or what?"

Among the 44 percent of Americans who identify as a Democrat, nearly 19 percent say they are a "strong" Democrat, 14 percent are "not very strong," and 12 percent think of themselves as independent but close to a Democrat. Millennials, Gen Xers, and Boomers are about equally likely to think of themselves as Democrats, with 41 percent of Gen Xers, 44 percent of Boomers, and 45 percent of Millennials doing so.

Among the 30 percent of Americans who identify as a Republican, 13 percent say they are a "strong" Republican, 9 percent are "not very strong," and 8 percent think of themselves as independent but close to a Republican. Millennials are much less likely than older generations to identify as Republican, with only 23 percent doing so. Among Gen Xers, 38 percent call themselves a Republican. The figure is 36 percent among Boomers.
