Sex segregation

Sex segregation, sex separation or gender segregation is the physical, legal, or cultural separation of people according to their biological sex. Sex segregation can refer simply to the physical and spatial separation by sex without any connotation of illegal discrimination. In other circumstances, sex segregation can be controversial. Depending on the circumstances, it can be a violation of capabilities and human rights and can create economic inefficiencies; on the other hand, some supporters argue that it is central to certain religious laws and social and cultural histories and traditions.[1][2]

Sex separation is common for public toilets and is often indicated by stick-figure gender symbols on the toilet doors.
