This report, Exploring How Disparities in Experiences of Violence and Substance Use Between Transgender and Cisgender Students Differ by Gender Expression, explores how a student’s perceived gender expression intersects with their gender identity to inform health risk. A robust and growing set of evidence shows that transgender youth face higher rates of violence, substance use and other negative health outcomes. This report looks at both the rates of negative outcomes within transgender students across three categories of gender expression and also at the disparities (or gaps) between cisgender and transgender students across these categories.
