I think people’s definition of boomer depends on their age. I’m 47, so by the definitions that move “boomer” qualifications to birth years in the mid 60’s… I’m a boomer.
But my dad wasn’t a WWII vet – which is part of the definition… He was a Korean war vet. And I’m the youngest of 3 kids…
Now my husband, 10 years older than me, is full on “boomer”. His dad served in WWII, came back, married, and started having kids.
boomers typically had to worry about Vietnam and were old enough to have been part of or observed the whole counter culture 60’s thing. I was in grade school during that era.
