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 ().
Healthcare and the LGBT community
Transgender people have higher levels of interaction with the police than the general population. 7% of transgender Americans have been held in prison cell simply due to their gender identity/expression. This rate is 41% for transgender African-Americans. 16% of respondents had been sexually assaulted in prison, a risk factor for HIV. 20% of trans women are sexually assaulted in prison, compared to 6% of trans men. Trans women of color are more likely to be assaulted whilst in prison. 38% of black trans women report having been sexually assaulted in prison compared to 12% of white trans women.
