Social mobility is the ability of individuals or families to move up or down the social ladder within society, which can be categorized into two main types: intragenerational mobility and __________ mobility.

The missing term is intergenerational mobility, which refers to the changes in social status between different generations within a family. For example, if a child grows up in a low-income household but later becomes a successful doctor, that child's rise in social status represents intergenerational mobility. This type of mobility highlights how opportunities and circumstances can change from one generation to the next. In contrast, intragenerational mobility looks at changes in a person's social status during their own lifetime. Together, these concepts help us understand how individuals and families can improve or decline in their social standing over time.
