“Did the Scout enrollment boom come from the Baby Boom?”
I do not think so.
I think my father said that he had been a scout. I guess it would have been in the 20s.
My brothers, 7 years older then me were scouts, early 50s, and me in mid to late 50s.
Naturally, there would have been a great increase from the baby boom, but that is just a matter of numbers, and little to do with culture.
historically, some 10% of boys have been involved in scouts and that level has mostly held over time. In my town, I have seen some drop off though.
