This PowerPoint provides an overview of the Trans Youth Project’s longitudinal study examining stability and change in gender identity and sexual orientation from childhood through adolescence. It includes background on the changing demographics of LGBTQ+ youth, key terminology definitions, and contrasts between traditional and contemporary approaches to gender development. The presentation covers study methodology with three participant groups (transgender, cisgender, and siblings) and key findings showing that most youth demonstrate stability in gender identity and sexual orientation over time, though significant minorities report changes. The slides examine childhood predictors of later identity development and discuss implications for understanding contemporary gender development, particularly highlighting the stability of early-identifying transgender children’s identities.
