"There were more babies born in 1946 than in any other year up until that time "
I'm not trying to hold you to only that year, and no other years had more. My older brother was born in '47. That makes him 67. I have two other sisters who are younger than him. The point is, there are more baby boomers who are not eligible for retirement, or haven't retired, than there are those who are. Census data shows this is true. Add in the census data that is showing baby boomers are working longer, and it brings into question the methodology used to calculate the labor participation rate.
