The demand for female labor is a central explanatory component of macrostru
ctural theories of gender stratification. This study analyzes how the struc
tural demand for female labor affects gender differences in labor force par
ticipation. The authors develop a measure of the gendered demand for labor
by indexing the degree to which the occupational structure is skewed toward
usually male or female occupations. Using census data from 1910 through 19
90 and National Longitudinal Sample of Youth (NLSY) data from 261 contempor
ary U.S. labor markets, the authors show that the gender difference in labo
r force participation covaries across time and space with this measure of t
he demand for female labor.
