A large number of people move up the social class ladder, a large number move down, and the social class system shows little change in exchange mobility.
Social mobility is the movement of a person's social position from one to another. The shift could be greater, lower, intergenerational, or intragenerational, and it's not always possible to tell whether it's for the better or worse.
