This may be the last presidential election dominated by Boomers and prior generations

For the past few decades, presidential elections have been dominated by voters of the Baby Boom and previous generations, who are estimated to have cast a majority of the votes. But their election reign may end this November, according to a new Pew Research Center analysis of census data.

Baby Boomers and prior generations have cast the vast majority of votes in every presidential election since 1980, data from the Census Bureau’s November Current Population Survey voting supplement show. In 2012, Boomers and previous generations accounted for 56% of those who said they voted. And these generations dominated earlier elections to an even greater degree. 

But the ranks of Millennial and Generation X eligible voters have been growing, thanks to the aging-in of Millennials and naturalizations among foreign-born adults. These generations matched Boomers and previous generations as a share of eligible voters in 2012 and are now estimated to outnumber them. As of July, an estimated 126 million Millennial and Gen X adults were eligible to vote (56% of eligible voters), compared with only 98 million Boomers and other adults from prior generations, or 44% of the voting-eligible population.

Although the electorate is increasingly comprised of younger generations, this does not imply that the electorate as a whole is getting younger.

Perhaps more importantly, eligible voters don’t necessarily translate into actual voters – that all depends on who shows up to vote on Election Day. Whether Millennial and Gen X adults outnumber Boomers and other generations in November will hinge on voter turnout.

In the 2012 election an estimated 70% of eligible voters in the Baby Boom, Silent and Greatest generations voted. Turnout among these generations was similar in 2004 (70%) and 2008 (69%).

If (and it’s a big if) 70% of Boomer-and-older eligible voters turn out in November, Millennials and Xers could match them even by turning out at much lower rates. A turnout rate of 70% among older voters would translate to 68.6 million votes. Millennials and Gen X could match that number of votes with a turnout rate of 54.5%. This level of turnout among the two younger generations seems plausible based on past elections.

In the 2012 election, 53.9% of Millennial and Gen X eligible voters turned out. Turnout among these generations was even higher in 2004 (54.2%) and higher still in 2008 (56.6%).

Historical patterns of voter turnout by generation also suggest the likely end of dominance by Boomers and prior generations. In general, as a generation ages, turnout rises, hits a peak, and then declines.

Among those in the oldest living generation, the Greatest Generation, turnout crested in the 1984 election at 76% before declining. Similarly, turnout among eligible voters in the Silent Generation peaked at 76% in the 1992 election. The Millennial and Gen X generations are likely still on the upswing in terms of their turnout rates, so it is a reasonable guess that at least 54.5% of these adults will vote, and perhaps more.

We won’t know until after November if Boomers and their elders will pass the torch to Gen X and Millennials as a share of voters, but all the available data suggest that the 2016 election will mark the beginning of a new era for U.S. presidential elections.

    My feeling is that the usefulness of naming generations is nearing an end. The boomers came of age at a time when social changes caused generational differences to be extreme, but in recent years the pace of generational change has slowed. Demographers cannot readily agree now on what the cut-off age for the millennial generation is because in many characteristics there is not that much difference between somebody coming of age now and somebody who came of age in 1999.

    It may be that future historians may find it more useful to name only the baby boomers as the generation that road the social changes between the generations before and the generations after.

    I disagree with Gen x years , although I am solidly Gen x , being born at the end of the year in 68. Someone born in 64 is not a boomr. My parents born in 47 have nothing g in common with some born in 1964. I would say Gen x is 1961-1975.

    The question is who are the majority of the young voters likely to vote for?

    I see the writing on the wall, but do these new generations 1) have a capacity to lead and 2) is there a group of civil servants in their generations willing to lead? Looking at the current crop of aspirants, they are not of their generation nor do I see or hear of anyone in the offing.
