Millennials overtake Baby Boomers as America’s largest generation

Millenials have surpassed Baby Boomers as the nation’s largest living adult generation, according to population estimates from the U.S. Census Bureau.

As of July 1, 2019, Millennials, whom we define as ages 23 to 38 in 2019, numbered 72.1 million, and Boomers ages 55-73, numbered 71.6 million.

Generation X numbered 65.2 million and is projected to pass the Boomers in population by 2028.

The Millennial generation continues to grow as young immigrants expand its ranks.

Boomers - whose generation was defined by the boom in U.S. births following World War II - are aging and their numbers shrinking in size as the number of deaths among them exceeds the number of older immigrants arriving in the country.

Because generations are analytical constructs, it takes time for popular and expert consensus to develop as to the precise boundaries that demarcate one generation from another.

In early 2018, Pew Research Center assessed demographic, labor market, attitudinal and behavioral measures to establish an endpoint - albeit inexact - for the Millennial generation.
