The transition to adulthood has become a thriving area of research in life
course studies. This review is organized around two of the held's emerging
themes. The first theme is the increasing variability in pathways to adult
roles through historical time. The second theme is a heightened sensitivity
to transition behaviors as developmental processes. Accounts of such proce
sses typically examine the active efforts of young people to shape their bi
ographies or the socially structured opportunities and limitations that def
ine pathways into adulthood. By joining these concepts, I suggest new lines
of inquiry that focus on the interplay between agency and social structure
s in the shaping of lives.
