Despite the gendered rebalancing of enrolments in higher education (HE) in the West, the underrepresentation of women in science, technology, engineering and mathematics (STEM) disciplines persists. Gendered selectivity of field of study influences higher education student migration (HESM) and in turn sheds light on HE participation. Framed by gender intersectionality theories both in HE studies and migration scholarship, this paper uses innovative data to analyse the intersectional effect of gender and field of study on HESM in Canada. Based on Statistics Canada's postsecondary student information system for the 2019/20 academic year, Canadian interregional flow matrixes structured by gender, field and level of study are constructed and analysed. The results show compelling evidence of the influence of gendered differences in HESM when intersected with field and level of study. Notably, women pursuing STEM studies migrate significantly more than any other grouping (i.e. gender, field and level of study groupings). The paper concludes with a discussion of policy implications for the influence of HESM on community demographic make-up and local labour markets, as well as future research including the need to understand gendered dimensions of migration intentions and motivations.
