In this longitudinal study, which is a follow-up analysis of a previous investigation (K. Marjoribanks, 2002a), the author examined environmental and individual influences on the likelihood of Australian young adults attending university. Participants were 5,181 Anglo-Australian (parents born in Australia, English was the language of the family), 460 Asian, 699 English (parents born in England), 746 European, and 163 Middle Eastern students (M age = 14.7 years, when the study began). The analyses indicated that Asian, European, and Middle Eastern young adults were more likely to attend university than were young adults from Anglo-Australian and English families, and young women had higher odds of attending university than did young men. Family social status variations in the likelihood of university attendance could be explained by differences in individual characteristics and proximal learning environments. Adolescents' individual characteristics and proximal learning environments combined to have a large independent association with the decision to attend university. (Contains 1 table.)
