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 ().
National Center for Transgender Equality
The National Center for Transgender Equality (NCTE) is a nonprofit social equality organization founded in 2003 by transgender activist Mara Keisling in Washington, D.C.. The organization works primarily in the areas of policy advocacy and media activism with the aim of advancing the equality of transgender people in the United States. Among other transgender-related issue areas, NCTE focuses on discrimination in employment, access to public accommodations, fair housing, identity documents, hate crimes and violence, criminal justice reform, federal research surveys and the Census, and health care access.
