A 2009 review of Medline literature suggests the total rate of patients expressing feelings of doubt or regret is estimated to be as high as 8%.A 2010 meta-study, based on 28 previous long-term studies of transsexual men and women, found that the overall psychological functioning of transsexual people after transition was similar to that of the general population and significantly better than that of untreated transsexual people. Prevalence
Estimates of the prevalence of transsexual people are highly dependent on the specific case definitions used in the studies, with prevalence rates varying by orders of magnitude. In the United States, the Diagnostic and Statistical Manual of Mental Disorders (DSM-V 2013) gives the following estimates: "For natal adult males [MTF], prevalence ranges from 0.005% to 0.014%, and for natal females [FTM], from 0.002% to 0.003%." It states, however, that these are likely underestimates since the figures are based on referrals to specialty clinics.The Amsterdam Gender Dysphoria Clinic over four decades has treated roughly 95% of Dutch transsexual clients, and it suggests (1997) a prevalence of 1:10,000 among assigned males and 1:30,000 among assigned females.Olyslager and Conway presented a paper at the WPATH 20th International Symposium (2007) arguing that the data from their own and other studies actually imply much higher prevalence, with minimum lower bounds of 1:4,500 male-to-female transsexual people and 1:8,000 female-to-male transsexual people for a number of countries worldwide. They estimate the number of post-op women in the US to be 32,000 and obtain a figure of 1:2500 male-to-female transsexual people.
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.
