Gender inequality is the social process by which men and women are not treated equally. The treatment may arise from distinctions regarding biology, psychology, or cultural norms prevalent in the society. Some of these distinctions are empirically grounded while others appear to be socially constructed. Studies show the different lived experiences of genders across many domains including education, life expectancy, personality, interests, family life, careers, and political affiliation. Gender inequality is experienced differently across different cultures and it also affects non-binary people.
