This course introduces students to the multi-disciplinary studies of careers and life courses. It reviews research traditions engaged in the studies of life histories and life courses, identifies their basic premises and key concepts, and examines how studies of careers and life courses can inform our understanding of social life. The implications of careers and life courses as imaginative frameworks will be discussed through an examination of the implications of the life course approach in the studies of aging, family changes, work careers, and social stratification and mobility.
