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 demographics of the United States
The Public Religion Research Institute (PRRI) survey of 2,314 Millennials found that 88% identified as heterosexual, 4% as bisexual, 2% as gay, and 1% as lesbian. In a separate question, 1% identified as transgender. In total, 7% of Millennials identified as LGBT. Three percent refused to identify their sexual orientation. The unaffiliated were more likely to identify as LGBT than the religious, as were Democratic-leaning Millennials compared to the Republican-leaning. No differences were found among the races.
