Gen Z = 71 million people
Millenials = 75.7 million
Gen X = 65 million
Boomers = 64 to 67 million
No, the Boomer generation is not that big. Not anymore now that the youngest of them are 62 years old and about 15 million from that generation are already dead.
There were 79 million Baby Boomers so they've been extremely influential for a couple of decades.
Even today and Trump is 80 years old, he is a Baby Boomer.
Trump, Obama, Clinton, and George W. Bush collectively represent 32 years of Baby Boomer presidential dominance, making them arguably the most politically dominant generation in American history.
Gen X?
Still no President.
