What is a defining characteristic of a caste system in social stratification?

A defining characteristic of a caste system in social stratification is that it is a rigid social hierarchy where people are born into specific groups that determine their social status and roles in society. In a caste system, individuals usually cannot change their caste, which means their opportunities, jobs, and social interactions are often limited by their birth. For example, in some cultures, a person born into a lower caste may not be allowed to pursue certain professions or marry someone from a higher caste. This creates a strong sense of inequality and can lead to discrimination based on caste. Overall, the caste system emphasizes that social position is largely predetermined and maintained over generations.
