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 ().

The 2008-09 National Transgender Discrimination Survey (NTDS)—a U.S. study by the National Center for Transgender Equality and the National Gay and Lesbian Task Force in collaboration with the National Black Justice Coalition that was, at its time, the most extensive survey of transgender discrimination—showed that Black transgender people in the United States suffer "the combination of anti-transgender bias and persistent, structural and individual racism" and that "black transgender people live in extreme poverty that is more than twice the rate for transgender people of all races (15%), four times the general Black population rate 9% and over eight times the general US population rate (4%)". Further discrimination is faced by gender nonconforming individuals, whether transitioning or not, due to displacement from societally acceptable gender binaries and visible stigmatization. According to the NTDS, transgender gender nonconforming (TGNC) individuals face between 8% and 15% high rates of self and social discrimination and violence than binary transgender individuals. Lisa R. Miller and Eric Anthony Grollman found in their 2015 study that "gender nonconformity may heighten trans people's exposure to discrimination and health-harming behaviors. Gender nonconforming trans adults reported more events of major and everyday transphobic discrimination than their gender conforming counterparts."
