I was born in the same year, and from what I can remember for years, I've always been referred to as Generation X...basically we're the baby boomers kids. I think the cutoff by most estimates is somewhere from 81-83.
My parents are the population boom that resulted from the end of the second world war.
So that's one way to look at it....part of this might have to include just when your parents were born...some estimate that it would either be between those who were born between 1943-1960 or between 1946 and 1964. My guess is that the cut off date should be sometime around the early 1960s.
My pop is Vietnam marine vet from the late 60s, and my brother was born in 1970.
Both of my parents were born in the late 1940s-- I just can't see myself in the same light as someone's parents who were born in the late 60's or 70s because those parents would have just become adults in the 80s and 90s...
Just to add some clarity on the generation differences.... A while ago, I asked my parents about their Hip Hop knowledge and what it was like in the 70s and early 80s and all they could say was "

...boy that was kid's music to us...we grew up on the Supremes, and the Four Tops...you ever seen Cooley High? That's what our times were like"
Now my brother and older cousins grew up on break dancing, beat boxing, the Fat boys, RUN DMC etc ...I remember all a dat when it was going down...and that is world's apart from what my parents experienced...
Plus...I would include knowledge about the internet, that's probably the biggest technological shift in the last 100 years, it's our modern day "industrial revolution"...and I remember life WELL before the internet became mainstream. Heck, I was still typing up my homework assignments on typewriters back then until processors really became a household product. And if you wanna throw cell phones in there...I can honestly say that no one that I knew had a cell phone in HS....that all become mainstream by the time I was a sophomore in college...shyt I still have my black Motorolla StarTec from 2000 that I refuse to throw out...
