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 ().
Transphobia
The 2015 United States Transgender Survey, the largest such survey ever carried out (with 27,715 respondents), found that one in ten respondents suffered transphobic violence at the hands of a family member and 8% were kicked out of their homes for being transgender. The majority of those who were openly transgender or perceived as transgender at school were victims of some form of mistreatment on account of this, including verbal abuse (54%), physical attacks (24%), and sexual assault (13%). 17% experienced such severe mistreatment that they had to leave school. Support from one's community or family was correlated with more positive outcomes related to mental health and social functioning.
