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
In 2015, "Schools In Transition: A Guide for Supporting Transgender Students in K-12 Schools" was introduced; it is a first-of-its-kind publication for school administrations, teachers, and parents about how to provide safe and supportive environments for all transgender students in kindergarten through twelfth grade. Its authors are the Transgender Youth Project Staff Attorney for the National Center for Lesbian Rights (NCLR), Gender Spectrum's Senior Director for Professional Development and Family Services, the National Education Association, the American Civil Liberties Union, and the Human Rights Campaign.
