Questions: Status Attainment and Occupational Mobility

Question 1

Blau and Duncan find that father's occupational status has both a direct and an indirect effect on son's occupational status. What does this mean, and what does each component tell us?

Model answer: The indirect effect is the portion of family-background influence that works through education — father's status shapes son's educational attainment, which then shapes occupational destination. The direct effect is family background's influence on occupational destination that cannot be accounted for by education alone. The direct effect indicates that something beyond formal credentials perpetuates family advantage: networks, cultural knowledge, class-specific dispositions, or direct connections to employers. Each component points toward different policy interventions — the indirect effect suggests educational access matters; the direct effect suggests that education alone is insufficient to equalize outcomes.

Path decomposition is a powerful analytical tool because it separates mechanisms. Understanding which portion of an effect is direct vs. mediated tells you where to intervene and what you would need to change to alter the outcome.

Question 2

Sewell's extended model adds 'significant others' influence' as a mediator between family background and educational attainment. Why would a sociologist include this rather than just measuring parental status and child outcomes directly?

Model answer: Including significant others' influence reveals the social mechanism through which family background shapes attainment — it is not simply that high-status parents pass resources to children, but that children from different class backgrounds develop different educational aspirations based on the expectations of parents, teachers, and peers. The mechanism is socialization of aspirations, not just resource transfer. This matters because it identifies an intervention point: if aspirations are shaped by significant others, then interventions that shift teacher expectations or peer norms might alter the attainment process independently of family resources.

Identifying mechanisms rather than just associations is the scientific goal of status attainment research. 'Family background predicts outcomes' is a description; 'aspirations mediated through significant others translate background into attainment' is an explanation that opens up intervention possibilities.
