Of the 27,715 transgender and genderqueer people who took the survey, 35% identified as "non-binary", 33% identified as transgender women, 29% identified as transgender men, and 3% said that "crossdresser" best described their gender identity.A 2016 systematic review and meta-analysis of "how various definitions of transgender affect prevalence estimates" in 27 studies found a meta-prevalence (mP) estimates per 100,000 population of 9.2 (95% CI = 4.9–13.6), equal to 1:11,000 for surgical or hormonal gender affirmation therapy and 6.8 (95% CI = 4.6–9.1), equal to 1:15,000 for transgender-related medical condition diagnoses. Of studies assessing self-reported transgender identity, prevalence was 355 (95% CI = 144–566), equal to 1 in 282. However, a single outlier study would have influenced the result to 871 (95% CI = 519–1,224), equal to 1 in 115; this study was removed. "Significant heterogeneity was observed in most analyses." Society and culture
A number of Native American and First Nations cultures have traditional social and ceremonial roles for individuals who do not fit into the usual roles for males and females in that culture. These roles can vary widely between tribes, because gender roles, when they exist at all, also vary considerably among different Native cultures. However, a modern, pan-Indian status known as Two-Spirit has emerged among LGBT Natives in recent years. Legal and social aspects
Laws regarding changes to the legal status of transsexual people are different from country to country. Some jurisdictions allow an individual to change their name, and sometimes, their legal gender, to reflect their gender identity.
The previous version, ICD-10, had incorporated transsexualism, dual role transvestism, and gender identity disorder of childhood into its gender identity disorder category. It defined transsexualism as "[a] desire to live and be accepted as a member of the opposite sex, usually accompanied by a sense of discomfort with, or inappropriateness of, ones anatomic sex, and a wish to have surgery and hormonal treatment to make ones body as congruent as possible with ones preferred sex." ICD-11 renamed Transexualism as Gender incongruence of adolescence or adulthood (HA60), and Gender identity disorder of childhood was renamed Gender incongruence of childhood (HA61). HA60 of the ICD-11 reads:Gender Incongruence of Adolescence and Adulthood is characterised by a marked and persistent incongruence between an individual´s experienced gender and the assigned sex, which often leads to a desire to ‘transition’, in order to live and be accepted as a person of the experienced gender, through hormonal treatment, surgery or other health care services to make the individual´s body align, as much as desired and to the extent possible, with the experienced gender. The diagnosis cannot be assigned prior the onset of puberty. [HA61 applies before puberty] Gender variant behaviour and preferences alone are not a basis for assigning the diagnosis.Historically, transsexualism has also been included in the American Psychiatric Associations Diagnostic and Statistical Manual of Mental Disorders (DSM). With the DSM-5, transsexualism was removed as a diagnosis, and a diagnosis of gender dysphoria was created in its place.
