Despite the growing demand for care economy employees (e.g., nurses, teachers, and social workers), men remain underrepresented in these careers. While economically developed countries support more equal rights for women and men, their labor markets are highly gender segregated (Charles 1992, 2003). We conducted a focused investigation of this paradoxical pattern in the care economy, testing whether gender gaps in care economy career interest are larger in more economically developed countries, and if so, what psychological and cultural factors underlie these patterns. We examined these questions with labor data from 70 countries (Study 1) and a pre-registered study of career interests among 19,240 university students from 49 countries (Study 2). Although more economically developed countries tend to promote greater gender equality, our results reveal the gender gap in care economy representation (Study 1) and interest (Study 2) is especially large in such countries. We did not observe parallel patterns for STEM representation or interest. Results from Study 2 supported an integrated theoretical account of this development paradox in care economy interest: Cross-national variation in the gender gap in care economy interest was predicted by country-level variation in economic development and individualism/collectivism but not by self-expression values or country-level gender equality, countering prior (controversial) claims of a gender equality paradox. Furthermore, larger gender gaps in communal values (e.g., men’s lower valuing of helping and caring for others) were a proximal predictor of larger gender gaps in care economy interest in highly economically developed countries.
