The term transgender was coined by John Oliven (1965) and popularized by various transgender people who pioneered the concept and practice of transgenderism. It is sometimes said that Virginia Prince (1976) popularized the term, but history shows that many transgender people advocated the use of this term much more than Prince. The adjective transgendered should not be used [...]. Transsexuals constitute a subset of transgender people."

Transsexualism is often included within the broader term 'transgender', which is generally considered an umbrella term for people who do not conform to typically accepted gender roles for the sex they were assigned at birth. The term 'transgender' is a word employed by activists to encompass as many groups of gender diverse people as possible. However, many of these groups individually don't identify with the term. Many health clinics and services set up to serve gender variant communities employ the term, however most of the people using these services again don't identify with this term. The rejection of this political category by those that it is designed to cover clearly illustrates the difference between self-identification and categories that are imposed by observers to understand other people.
