The Production of Inequalities within Families and Across Generations: The Intergenerational Effects of Birth Order and Family Size on Educational Attainment
There has long been interest in the extent to which effects of social stratification extend and persist across generations. We take a novel approach to this question by asking whether birth order and sibling group size in the parental generation influences the educational attainment of their children. To address this question we use Swedish population data on cohorts born 1960-1982. To study the effects of parental birth order and family size we apply a cousin fixed effects design and exploit information on twin births in the parents generation. Relative to having a first-born mother, having a second-born or fifth-born mother is associated with educational attainment at age 30 being 4% and 8% of a standard deviation lower, respectively. After adjusting for attained parental education and social class, the parental birth order effect is heavily attenuated. Nevertheless, we do find that children who share the same birth order and gender as their parents attain slightly more education, and this is particularly pronounced when the parents have higher levels of education themselves. We do not find clear or consistent evidence for parental sibling group size effects. Overall our results suggest that birth order and family size effects operate through a Markovian process of transmission.
