Notes: other covariates are Age, Age at first birth, Boy 1st, Boy 2nd, Black, Hispanic and Other race. No Wald estimate for married women is printed: Table 5's Wald estimates use the all-women sample (its first stage is Table 6 column (1), not column (4)), which the Fertility file does not hold, so Table 7's 2SLS cell is the married-women weeks-worked target."
