The movement between social classes that occurs during the course of an individual’s lifetime

sociali mobility

Explanation:

Social mobility is the movement of individuals that enables chances and opportunities for underprivileged sectors of society, to break the conditions of poverty or their social class into higher social classes.

This means a change in social status, as well as the quality of life that they can experience.

The social mobility tendencies are measured by variables like occupational status, individual earnings and total family income.

A very important factor often reflecting change is the amount of free time to be spent on leisure activities. With a higher social class, the availability for families to spend time in free time will rank them higher.

This change can be  seen in the course of the individual life time or measured within generations as well.
