U.S. demographics
Baby Boomers are those born between the years 1946 and 1964, dominated largely by the massive population explosion that followed World War Two. Millennials (1981-1997) are those who came after generation X, the group born between 1965 and 1980, a group who have never been, and will never be, in the lead population-wise.
Millennials now number, according to the Census Bureau stats, examined by the Pew Research Center, 75.4 million, surpassing the 74.9 million baby boomers. Generation X, the Pew Research Center predicts, will reach a peak of about 65.4 million in 2018 and won’t surpass baby boomers to take second until 2028.
Naturally there cannot be any new births in the millennial age-group, but their numbers are on the rise due to immigration, especially in the 18-24 age group.
Meanwhile, baby boomers are dying off in greater numbers than they are being augmented by the arrival of older immigrants in their age group.
Another population stat recently released by Pew Research concerns centenarians, those 100 or older. According to new numbers, in 2015 there were half-a-million people on Earth aged 100 or older but by 2050 that number is expected to swell to 3.7 million.
