What type of social mobility is represented by Louie's family moving from lower class to upper class over generations?

The concept of intergenerational mobility refers to changes in social status that occur from one generation to the next within a family. Louie's family's transition from lower class to upper class over generations demonstrates this type of mobility, as it highlights the movement between social classes across different generations. This form of mobility emphasizes how social conditions, opportunities, and achievements can alter the social standing of future generations, rather than the individual experiences of a single generation.

In this context, the other types of mobility do not apply. Intragenerational mobility pertains to changes in a person's social standing within their own lifetime. Structural mobility involves changes in the social structure that enable individuals to move up or down the social ladder, typically as a result of external factors affecting the entire society. Horizontal mobility describes a change in position or job without a change in social status, such as moving from one similar job to another. Therefore, intergenerational mobility is the most fitting concept for the situation described regarding Louie's family's social ascent.
