Family size in successive generations: The effects of birth order,intergenerational change in lifestyle,and familial satisfaction

Studies of family size in successive generations have found a small but persistently positive effect of size of family of orientation. Recent work has suggested that this relationship may be influenced by birth order, intergenerational change in lifestyle, and familial satisfaction. Data from a 24-year longitudinal study of women in Pennsylvania indicate that number of siblings does influence size of family of procreation. More important, this relationship is stronger among women who were first-born that later-born, stronger for those not experiencing intergenerational change than for those who changed, and stronger among those who at age 16 were satisfied with their parental family than for those who were dissatisfied.
