Lateral mobility is the geographical movement of individuals or groups from one region to another.
Vertical mobility is movement up and down a hierarchy of stratification.
Those who gain in property, income or status are said to be upwardly mobile, while those who move in the opposite direction are said to be downwardly mobile. Intergenerational mobility compares the present social position of individuals with their parents. Intragenerational mobility compares the position of the same individual at different moments in the course of his or her working life. A further important distinction made in studies of social mobility is between structural and nonstructural mobility. Structural mobility is movements made possible by changes in the occupational structure in society.
