Current understandings of gender and sexual identities are limited given the diversity of the LGBTQ + community. Researchers and clinicians are constantly challenged by the ever-expanding identity options. The current analysis seeks to bring awareness to the importance of moving beyond traditional binary gender identity and sexual identity categories when working with Millennial and Generation Z LGBTQ + populations. A sample of 1863 LGBTQ + young adults (M[subscript age] = 19.54, SD = 3.33, range= 18-35) reported on their gender identities and sexual identities. We found that 40% of our sample endorsed an expansive sexual identity while 34% endorsed an expansive gender identity. We also found differences between participants based on generational cohorts. Generation Z participants were more likely to report an expansive gender and sexual identity, when compared to Millennials. This data serves to inform researchers and clinicians as they continue work with, and serve, LGBTQ + communities.
