Entangled, I don't think there is a right age to move out. I think it is dependent on levels of things like maturity, responsibility....and whether or not you have the financial means to take care of yourself.

When I "lived at home" I had periods where I was homeless and then, there were times I just ran the streets. I officially moved out when I was 17.

If I had a fairly stable home life and a choice, today I would choose to go to college before moving out.
