In relation to gender equality, vertical segregation refers to the concentration of women and men in different grades, levels of responsibility or positions. It indicates the under- (or over-) representation of women and men workers in occupations or sectors at the top of an ordering based on ‘desirable’ attributes (income, prestige, job stability, etc.), independent of the sector of activity.
