Additional notes and information
Collectively, gender roles often determine the traditional responsibilities and tasks assigned to women, men, girls and boys (see gender division of labour). Gender-specific roles are often conditioned by household structure, access to resources, specific impacts of the global economy, occurrence of conflict or disaster, and other locally relevant factors such as ecological conditions. Like gender itself, gender roles can evolve over time, in particular through the empowerment of women and transformation of masculinities.
