Transgender
One effort to quantify the population gave a "rough estimate" that 0.3 percent of adults in the US are transgender, overlapping to an unknown degree with the estimated 3.5 percent of US adults (1-in-30) who identify as LGBT. More recent studies released in 2016 estimate the proportion of Americans who identify as transgender at 0.5 to 0.6%. This would put the total number of transgender Americans at approximately 1.4 million adults ().
History of transgender people in the United States
Three groups - the Girl Scouts, the North American Gay Amateur Athletic Alliance, and the Episcopal Church in the United States - announced their acceptance of transgender people in this decade. In 2011, after the initial rejection of Bobby Montoya, a transgender girl, from the Girl Scouts of Colorado, the Girl Scouts of Colorado announced that "Girl Scouts is an inclusive organization and we accept all girls in Kindergarten through 12th grade as members. If a child identifies as a girl and the child's family presents her as a girl, Girl Scouts of Colorado welcomes her as a Girl Scout." Also in 2011, the North American Gay Amateur Athletic Alliance changed its policy to include transgender and bisexual players. In 2012 the Episcopal Church in the United States approved a change to their nondiscrimination canons to include gender identity and expression.
