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
In May 2015, six Michigan transgender people filed "Love v. Johnson" in the United States District Court for the Eastern District of Michigan, challenging the state's policy requiring the information on a person's driver's license match the information on their birth certificate. This policy requires transgender people to change the information on their birth certificates in order to change their driver's licenses, which is not possible in Tennessee, Nebraska and Ohio, where three of the plaintiffs were born, and requires a court order in South Carolina, where a fourth was born. The remaining two residents were born in Michigan, and would be required to undergo surgery to change their birth certificates. The plaintiffs in the case are represented by the American Civil Liberties Union.
