Millennials are America’s largest generation, helped by immigrants
Millennials, whom Pew Research Center defines as those ages 18-34 in 2015, now number 75.4 million, surpassing the 74.9 million Baby Boomers (ages 51-69). And Generation X (ages 35-50 in 2015) 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 older and their numbers shrinking as the number of deaths among them exceeds the number of older immigrants arriving in the country.
With immigration adding more numbers to its group than any other, the Millennial population is projected to peak in 2036 at 81.1 million.
Thereafter the oldest Millennial will be at least 56 years of age and mortality is projected to outweigh net immigration. By 2050 there will be a projected 79.2 million Millennials.
Many Millennials are immigrants or the children of immigrants who arrived in the United States as part of an upsurge in immigration that began in the 1940s.
The share of people age 20 to 34 who were born in a foreign country is now around 15 percent — much higher than it was in 1950 and near the peak of almost 20 percent seen in 1910 during the last great wave of immigration to the United States. ■
