If you've never read my blog before, you may not realize I was born and raised in NYC, about 1 mile from Shea Stadium. I left Queens at age 26, at which time I relocated to NE Pennsylvania. Which means more than half of my life was spent growing up in NYC.
Sen. Joe Biden was, indeed, born in Scranton, PA. His family moved when he was 10. Sen. Biden is 65.
I can't point to anything specific that says when you've lived x years away from your place of birth, you can no longer state you're from that place. However, if you've lived 55 years in one state, that pretty much trumps the 10 years of your youth spent in another state.
