Education, occupation, and income are the main indicators of social mobility. Education provides opportunities for upward mobility and helps individuals gain credentials for better jobs. Occupation determines social status, and income level influences an individual's social position. There are different types of social mobility, including upward mobility to higher statuses, downward mobility, and horizontal or geographic mobility without changes in status. Intergenerational mobility involves changes across generations, while intragenerational mobility refers to changes within one's lifetime. Social mobility benefits societies by allowing the most able individuals to fill positions regardless of background.
