This article investigates the long-term impact of early maternal employment
on children's cognitive and behavioral outcomes. Non-Hispanic White and Af
rican American children aged 3 to 4 in the 1986 National Longitudinal Surve
y of Youth were followed longitudinally to see whether the effects that pri
or studies found at age 3 to 4 persist into the school-age years (ages 7 to
8) or whether those effects attenuate over rime. The empirical results ind
icate that maternal employment in the Ist year of a child's life has signif
icant negative effects on White children's cognitive outcomes. These effect
s persist to ages 7 or 8 for some children bur not for others. We also foun
d some negative effects of maternal employment in the Ist year on behaviora
l problems as assessed at age 7 or 8, but again these effects are found onl
y for White children.
