How prevalent is gender identity disorder?

The term "gender identity disorder" is outdated and considered offensive by many transgender and non-binary individuals. The preferred term is gender dysphoria, which refers to the distress a person may experience due to a mismatch between their gender identity and the sex they were assigned at birth.

The prevalence of gender dysphoria varies depending on the population studied and the criteria used for diagnosis. According to a 2016 study published in the Journal of the American Medical Association Psychiatry, the estimated prevalence of gender dysphoria among adults in the United States is 0.6%, or about 1.4 million people. However, it's important to note that this study only included individuals who sought treatment for gender dysphoria, so the actual prevalence may be higher.

Other studies have found similar rates of gender dysphoria among adolescents and children. A 2017 study published in the journal Pediatrics found that the prevalence of gender dysphoria among transgender adolescents was 1.8%, or about 150,000 people in the United States.

It's important to note that these estimates are based on self-reported data, which may be subject to bias and underreporting. Additionally, the prevalence of gender dysphoria may vary across different cultures, countries, and time periods.
