This report provides insightful analysis of the results of the Trevor Project’s 2019 National Survey on LGBTQ Youth Mental Health, which surveyed over 34,000 LGBTQ youth ages 13-24. The executive summary documents in graphs and text the significant increase in gender diversity of LGBTQ youth. For example, “One in four LGBTQ youth identified outside of the gender binary. More specifically, 25% selected gender queer/gender nonconforming, a different identity, or chose multiple identities. Within the gender binary, 7% of youth exclusively selected transgender man or transgender woman.”
