How many people comprise the "baby boomer" generation in the U.S.?

Answer 1

Boomers were all people born between 1946 and 1964. That would put their current ages from 42 to 60. Checking the census site, the last comprehensive #'s are from 2000, so the boomers would've been 36 - 54 then. Here are the numbers:

35 to 44 years
45,148,527

45 to 54 years
37,677,952
