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 ().
LGBT people in prison
In 2011, the National Transgender Discrimination Survey found that 35% of black transgender Americans have been incarcerated simply due to perceived anti-trans bias, compared to 4% of white transgender respondents. Black transgender people had higher rates of experiences of incarceration in general (47% compared to 12% of white transgender people). It also found that black trans women were sexually assaulted in jail at a rate of 38%, compared to 12% of white trans women prisoners.
