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 ().
Transgender rights in the United States
There is no federal law designating transgender as a protected class, or specifically requiring equal treatment for transgender people. Some versions of the Employment Non-Discrimination Act introduced in the U.S. Congress have included protections against discrimination for transgender people, but as of 2015 no version of ENDA has passed. Whether or not to include such language has been a controversial part of the debate over the bill. In 2016 and again in 2017, Rep. Pete Olson [R-TX] introduced legislation to strictly interpret gender identity according to biology, which would end federal civil rights protection of gender identity. It remains legal at the federal level for parents to subject transgender children to conversion therapy.
