Women’s educational attainment, marriage, and fertility: Evidence from the 1944 G.I. Bill

In contemporary settings, greater earnings among women are typically associated with reduced marriage rates and lower fertility. One way that women’s earnings may increase is via changes in educational attainment. To study whether educational attainment affects marriage and fertility choices in a historical setting, I rely on the variation in educational attainment among female WWII veterans created by the 1944 G.I. Bill. Using data from the long-form 1980 census, I first show that WWII veteran status is associated with reduced rates of marriage, increased age at first marriage, and lower fertility, which suggests that G.I. Bill-related education could have had an important effect for veteran women. I then use age at the time of the G.I. Bill announcement as an instrument to establish a causal effect of educational attainment on marriage and fertility outcomes among female veterans. My instrumental variable estimates suggest that each year of G.I. Bill-induced educational attainment is associated with an 8 percentage point decrease in the probability of ever getting married, a 4.7 year increase in age at first marriage, and a 0.67 reduction in the number of children. Using age at the time of the G.I. Bill announcement as an instrument is valid because the benefits could not have been easily anticipated, women had to be 21 to enlist, and the generosity of one’s G.I. Bill benefits depended on the number of years of WWII service.
