Cohort, gender, ethnicity, culture, and socioeconomic status are all social factors that influence individuals' expectations and trajectories of life decisions. For example, individuals from lower socioeconomic backgrounds may have limited access to education and job opportunities, which could impact their career choices and earning potential. Additionally, cultural norms and beliefs may shape individuals' attitudes towards marriage, family, and other life decisions. These social factors can interact with each other and with an individual's personal characteristics, such as personality and interests, to shape their life course.
