One in four Americans is a Millennial, a member of the nation's largest generation. According to a Demo Memo analysis of the Census Bureau's population estimates, Millennials became the largest generation in 2011 when they outnumbered Boomers by just 332,000. In 2015, Millennials outnumbered Boomers by 4 million.

Between 2010 and 2015, the number of Millennials grew by 2.2 million thanks to immigration. The number of Baby Boomers shrank by 2.5 million as the aging generation faced higher mortality rates. The number of Older Americans fell by 9 million during those years.
