Sex segregation is the separation of people according to their sex.

The term gender apartheid (or sexual apartheid) also has been applied to segregation of people by gender, implying that it is sexual discrimination. In some circumstances, gender segregation is a controversial policy, with critics contending that in most or all circumstances it is a violation of human rights, and supporters arguing that it is necessary to maintain decency, sacredness, modesty, female safety, or the family unit.

In almost all parts of the world, places for activities which involve nudity – for example, showers, toilets, changing rooms – are usually segregated by sex.^{[citation needed]} There are exceptions to this: clothing-optional beaches and art classrooms for figure drawing are generally not segregated. Saunas and baths may or may not be, depending on the culture.

The degree of segregation can vary. In some places, separate changing rooms for men and women are the norm, while elsewhere, a single change room with cubicles is normal. With the widespread practice of groping women in crowded public places (e.g. street harassment or eve teasing), some countries have designated women-only passenger cars or compartments on trains.

George Albert Godley (31 October 1857 – 20 July 1941) was a police officer of the Metropolitan Police who was involved in the hunt for Jack the Ripper in 1888.

Born at East Grinstead in Sussex in 1857, Godley initially worked as a sawyer. He then joined the Metropolitan Police on 26 February 1877, and was assigned warrant number 61230. At the time of the Jack the Ripper murders in 1888 Godley was a Sergeant in London's J Division (Bethnal Green). He transferred to H Division (Whitechapel) where he assisted Inspector Frederick Abberline in the hunt for the killer. The Times of 12 November 1888 reported:

"Since the murders in Berner Street, St. Georges, and Mitre Square, Aldgate, on September 30th, Detective Inspectors Reid, Moore and Nairn, and Sergeants Thick, Godley, M'Carthy and Pearce have been constantly engaged, under the direction of Inspector Abberline (Scotland Yard), in prosecuting inquiries, but, unfortunately, up to the present time without any practical result. As an instance of the magnitude of their labours, each officer has had, on average, during the last six weeks to make some 30 separate inquiries weekly, and these have had to be made in different portions of the metropolis and suburbs. Since the two above-mentioned murders no fewer than 1,400 letters relating to the tragedies have been received by the police, and although the greater portion of these gratuitous communications were found to be of a trivial and even ridiculous character, still each one was thoroughly investigated. On Saturday (10th November) many more letters were received, and these are now being inquired into."
