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 what it means to be male versus female. For a more detailed distinction on the division between the two, see sex and gender distinction. This article focuses specifically on sex segregation.
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.
