This sums up a report issued this month by the Williams Institute, for the American Foundation for Suicide Prevention.
Paragraph one of the report:
The prevalence of suicide attempts among respondents to the National Transgender Discrimination Survey (NTDS), conducted by the National Gay and Lesbian Task Force and National Center for Transgender Equality, is 41 percent, which vastly exceeds the 4.6 percent of the overall U.S. population who report a lifetime suicide attempt, and is also higher than the 10-20 percent of lesbian, gay and bisexual adults who report ever attempting suicide. Much remains to be learned about underlying factors and which groups within the diverse population of transgender and gender non-conforming people are most at risk.
Here's a link to the report. It has been added to our "Articles and Papers" section on the right side of the T-Central home page.
