Sex segregation
Sex segregation is the physical, legal, and cultural separation of people according to their biological sex. This is distinct from gender segregation, which is the separation of people according to social constructions of gender.In certain circumstances, sex segregation is controversial. Some critics contend that it is a violation of capabilities and human rights and can create economic inefficiencies, while some supporters argue that it is central to certain religious laws and social and cultural histories and traditions.
