"The 2015 U.S. Trans Survey (USTS) is the follow up to the National Transgender Discrimination Survey, the largest survey ever devoted to the lives and experiences of trans people. The study was developed and conducted by the National LGBTQ Task Force and the National Center for Transgender Equality in 2008- 2009, and the results were released in the 2011 report: Injustice At Every Turn. As the single-most cited study about trans people—cited by media over 15,000 times—it has dramatically changed how the public and policymakers understand the challenges facing trans people."
