In Vietnam, it is commonly believed that gender norms, sex labour segregation, and structural organization of social institutions often favour male dominance while restricting women’s roles in domestic spheres. However, there is a scant literature of Vietnamese scholarship on the determinants of gender role attitudes, especially geographical disparities. This paper aims to fill this void by using a nationally representative survey with 8288 respondents. Our findings suggested that age, marital status, religion, education, living area, region, ethnicity, and personal monthly income are the factors that predicted gender attitudes. In terms of regional disparities, we found that Northerners were more permissive in their gender attitudes than Southerners, which may be explained by distinct historical and political trajectories in Northern and Southern Vietnam during the last century. There were, however, inconsistent patterns among different age cohorts whereby region significantly impacted the attitudes of women born before the end of the French War in 1954, men born after the Reunification in 1975, as well as both men and women born between 1954 and 1975.
