Different studies have arrived at different conclusions about the prevalence of<unk> . The DSM-5 estimates that about 0.005% to 0.014% of people assigned male at birth and 0.002% to 0.003% of people assigned female at birth are diagnosable with<unk> . According to Black's Medical Dictionary,<unk>  “occurs in one in 30,000 male births and one in 100,000 female births.” Studies in European countries in the early 2000s found that about 1 in 12,000 natal male adults and 1 in 30,000 natal female adults seek out sex reassignment surgery. Studies of hormonal treatment or legal name change find higher prevalence than sex reassignment, with, for example a 2010 Swedish study finding that 1 in 7,750 adult natal males and 1 in 13,120 adult natal females requested a legal name change to a name of the opposite<unk> . Studies that measure transgender status by self-identification find even higher rates of<unk>  identity different from sex assigned at birth (although some of those who identify as transgender or<unk>  nonconforming may not experience clinically significant distress and so do not have<unk> . A study in New Zealand found that 1 in 3,630 natal males and 1 in 22,714 natal females have changed their legal<unk>  markers. A survey of Massachusetts adults found that 0.5% identify as transgender. A national survey in New Zealand of 8,500 randomly selected secondary school students from 91 randomly selected high schools found 1.2% of students responded "yes" to the question "Do you think you are transgender?". Outside of a clinical setting, the stability of transgender or non-binary identities is unknown. Research indicates people who transition in adulthood are up to three times more likely to be male assigned at birth, but that among people transitioning in childhood the sex ratio is close to 1:1. The prevalence of<unk>  in children is unknown due to the absence of formal prevalence studies.
