Choosing a Major and a Partner: Field of Study and Union Formation Among College-Educated Women in Europe.

In this paper, we explore the patterns of assortative mating among college-educated women who graduated from typically female, typically male, or mixed disciplines. Using a set of cross-sectional observations of a single cohort of female graduates (2010) from European Union Labour Force Survey data and applying multilevel multinomial logit models, we estimated the relative risk of living with a college-educated partner (homogamy), living with less educated partner (hypogamy), or being single. Focusing on the first five years after graduation, the analysis demonstrated that field of study is a significant predictor of mating behaviour. Women with degrees in male-dominated fields are less likely to partner down with less educated men. The mating advantage of women from male-dominated fields is stronger in countries with a higher female employment rate. Furthermore, more liberal gender roles seem to increase the level of singlehood among women from male-dominated fields. Finally, women from female-dominated and mixed disciplines are more likely to partner down if the man graduated from a male-typical discipline. However, among women from male-dominated disciplines, such a trade-off was not observed.
