Much as the "flower power" generation would disagree, in my opinion, the Baby Boomer generation lasted to 1950-53 only. The "bb" generation was an abbreviation to mean those conceived toward the last days WW2. It was a generation that would grow up in peace time environment with retooling factories for the needs of building articles for domestic use.
I'm both a Millennial and a Xennial. Born in 1981 I'm of the age where I didn't start using the internet properly until I was about 20. Not like the kids nowadays who have not known a world without it. I vaguely remember me and my mate Neil going to an internet café in Manchester in 1997 and he was showing me the internet and I had no idea what was gong on. I'm only 16 days younger than Donkey Kong.
1952....I'm a solid Boomer I guess. Every family seemed to have 3-5 kids in those days, 5 in our family. Most families around us had somewhat the same. After that, it seemed 1 or2 were the norm. It was a baby boom for sure.
I'm a boomer too and came from a family of 5 as did most of my cousins and their families. Dad came from a family of 13 so I've a ton of cousins. Mom had only her brother who had 2 girls. Interestingly enough, there were 2 boys in my family and only 1 boy in each of my dad's sibblings families so lots of girls but not so many boys.
