  1. The variables of sibling sex composition for models (1) to (3) are ‘have brothers,’ ‘have sisters,’ and ‘proportion of female siblings,’ respectively. Data are weighted according to the sampling probabilities. Standard error for clustering robustness in parentheses. *p < 0.1; **p < 0.05; ***p < 0.01.
