Occupational gender stereotypes develop from early age and contribute to occupational gender imbalance. Previous research used questionnaires or interviews to investigate children's explicit stereotypes and where drawings have been used, mostly men-dominated occupations have been considered. This study used drawings and interviews to assess implicit stereotypes of both men and women-dominated occupations and whether children's sex, age and cultural background predicted these stereotypes. Two hundred and forty-three 6-to-7-year-olds and 10-to-11-year-olds in Britain and Argentina-encompassing both Global South and Global North perspectives- drew five human figures: (i) person of their choice, (ii) dancer, (iii) nanny (iv) firefighter and (v) pilot. In interviews, children confirmed and justified their gender choices for each drawing. Results indicate gender stereotypes in children from both countries, especially towards women-dominated occupations. Girls exhibited more rigid gender views than boys. These findings suggest widespread and culturally consistent occupational gender stereotypes, potentially limiting children's future job choices.
