There is some disagreement as to the exact beginning and end dates of the baby boom, but the range most commonly accepted is as starting in 1946 and ending in 1964.[2][3][4] The problem with this definition is that this period may be too long for a cultural generation, even though it covers a time of increased births. If the gross number of births were the indicator, births began to decline from the peak in 1957 (4,300,000), but fluctuated or did not decline by much more than 40,000 (1959-1960) to 60,000 (1962-1963) until a sharp decline from 1960 (4,027,490) to 1965 (3,760,358). This makes 1964 a good year to mark the end of the baby boom in the U.S.[5]

Maybe you are a SHADOW BOOMER?
In his book Boomer Nation, Steve Gillon states that the baby boom began in 1946 and ends in 1960, but he breaks Baby Boomers into two groups: Boomers, born between 1945 and 1957; and Shadow Boomers born between 1958 and 1964.[6]
I was born in 63 so that makes me a shadow boomer I guess. I’ve long excepted that I am lumped in with the boomers as a constituency. Read many articles that place it at 64. What this means to me is that I’ll be one of the last men standing from this constituency long after it has sucked the gov’t tit dry and long after it has any political power in my twilight years. It behooves us 40 somethings to reform these government “handout to the aged” programs.
