Not sure that is right, I see it more as a generational than location based thing. In the N/E USA where I was born, my generation was kicked out on the street before the ink dried on the diploma, but my sisters generation (she is much much younger) stays home much longer.
Still though, in most of the families I know in the n/e USA - once the kid is out, they stay out.
