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 legal history in the United States
On June 30, 2016, Ash Carter announced that the ban on transgender people from openly serving in the US military had been lifted and that the United States Department of Defense was undergoing a twelve-month transition period to satisfy the needs of transgender soldiers. Just over a year later, in July 2017, President Donald Trump tweeted that transgender personnel would again be barred from the military, and he published a memo on August 25, 2017 directing that an implementation plan for a transgender ban be submitted to him by the Secretary of Defense and the Secretary of Homeland Security by February 2018.
