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 disenfranchisement in the United States
The National Gay and Lesbian Taskforce's 2011 National Transgender Discrimination Survey finds that only 21% of people who identify as transgender have been able to update all of their IDs and records to reflect their gender; 33% have not updated any IDs.
