Notes: Add Health regressions control for age, age squared, gender, birth order, mother’s education, picture vocabulary score and the first 20 ancestry-specific principal components of the genetic data. HRS regressions control for age, age squared, gender, mother’s education and the first 10 ancestry-specific principal components of the genetic data. Heteroscedasticity-robust standard errors in parentheses.
