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 ().
Homeless shelter
Approximately 40% of all homeless youth in the United States identify as LGBT (Lesbian, Gay, Bisexual, Transgender). In San Francisco, approximately 29% of all the homeless in that city are on the LGBT spectrum. The National Center for Transgender Equality reports that 1 in 5 transgender individuals has experienced being homeless at least once in their lives.
