Moving beyond occupational aspirations to actual selection of occupations, the current research considers the impact of individual gender beliefs on selection of occupations for men who work in male-dominated occupations compared to men who work in mixed-sex or female-dominated occupations and for women who work in female-dominated occupations compared to women who work in mixed-sex or male-dominated occupations. Using a nationally representative sample from the General Social Survey, I compare the sex composition of occupations and responses to survey questions regarding gender beliefs for analyzing the impact of gender beliefs on the occupations people choose. I examine gender beliefs involving women’s roles outside the home and beliefs regarding homosexuality, political views, and religiosity. I find that compared to other men, men who have traditional gender beliefs regarding the role of women in the private sphere are more likely to have male-dominated occupations than mixed-sex or female-dominated occupations. As men’s level of education increases, however, the relationship between these variables no longer reaches statistical significance and the likelihood of men working in male-dominated occupations decreases. I also find that compared to other men, men who believe that homosexual relations are wrong are more likely to work in male-dominated occupations than in mixed-sex or female-dominated occupations. For women, however, the impact of gender beliefs on selection of occupations is not statistically significant. These findings have implications for determining methods for eliminating occupational sex segregation.
