Geographic distance and contact between middle-aged children and their parents: the effects of social class over 20 years.

This research derives and tests hypotheses from two alternative conceptual models: the modified extended family model, and the changing family constraints model, which takes into account recent changes in work and family life. The hypotheses address social class differences in geographic distance and contact frequency between middle-aged children and their parents over time. Simultaneous probit models are used to analyze distance and contact as jointly determined outcomes with data from the USC Longitudinal Study of Generations and Mental Health. Results from these analyses indicate that children's 1971 educational aspirations and social class positions predict 1991 distance and contact between generations. Parents who have lower 1991 incomes, however, live farther from children and talk with them on the telephone less frequently than higher-income parents. Thus, the effects of early social class position support the modified extended family model, whereas the effects of current social class position support the changing family constraints model.
