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 ().
Homosexuality
In the United States, according to a report by "The Williams Institute" in April 2011, 3.5% or approximately 9 million of the adult population are lesbian, gay, or bisexual. According to the 2000 United States Census, there were about 601,209 same-sex unmarried partner households.
