Table 2.

Regressions of reproductive performance (a: total fertility and b: number of offspring surviving to age 5) as a function of work time, done separately for husband’s and wife’s and then for combined husband’s and wife’s work time. Each row refers to a multiple regression that controls for husband’s and wife’s ages.
