Sibling Correlates of Young Adults' Status Attainment: Ethnic Group Differences

I used longitudinal data to examine relationships between sibling variables and young adults' status attainment at different levels, based on earlier measures of adolescents' educational and occupational aspirations. My 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. My study showed that the number of children in a family and birth order continue to be significantly associated with young adults' status attainment, even after incorporating the mediating influences of adolescents' aspirations. The investigation also suggested ethnic group differences among sibling variables, adolescents' aspirations, and young adults' status attainment.
