Ethnicity, sibling, and family correlates of young adults' status attainment: a follow-up study.

Longitudinal data were used to examine relationships among sibling variables, perceptions of family environments, and measures of educational attainment, occupational status, and occupational aspirations. The analyses involved 21-year-old Australians from Anglo-Australian, Greek, and Southern Italian families. Regression surfaces were plotted from models that included terms to test for possible linear, interaction, and curvilinear associations among the variables. The study indicated that sibsize and birth order continued to have many significant associations with young adults' status attainment even after taking into account the mediating influence of perceived family environments. Also, the investigation suggested that there are ethnic-group differences in relations among sibling variables, perceived parents' support for learning, and young adults' status attainment.
