The Longitudinal Study of Generations (LSOG), initiated in 1971, began as a survey of intergenerational relations among 300 three-generation California families with grandparents (then in their sixties), middle-aged parents (then in their early forties), and grandchildren (then aged 15 to 26). The study broadened in 1991 and now includes a fourth generation, the great-grandchildren of these same families.
The study objectives were:
To track life-course trajectories of family intergenerational solidarity and conflict over three decades of adulthood, and across successive generations of family members;
To identify how intergenerational solidarity and conflict influence the well-being of family members throughout the adult life-course and across successive generations;
To chart the effects of socio-historical change on families, intergenerational relationships, and individual life-course development during the past three decades;
To examine women’s roles and relationships in multigenerational families over 30 years of rapid change in the social trajectories of women’s lives.
