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 ().
Lesbian
Lesbians in the U.S. are estimated to be about 2.6% of the population, according to a National Opinion Research Center survey of sexually active adults who had had same-sex experiences within the past year, completed in 2000. A survey of same-sex couples in the United States showed that between 2000 and 2005, the number of people claiming to be in same-sex relationships increased by 30%—five times the rate of population growth in the U.S. The study attributed the jump to people being more comfortable self-identifying as homosexual to the federal government.
