Sexual identity development milestones mark the ages at which sexual minority people first experience key developmental events including same-sex attraction, self-realization of a sexual minority identity, same-sex sexual behavior and romantic relationships, and sexual identity disclosure. Most studies of milestones use variable-centered, rather than person-centered approaches, potentially obscuring diversity in patterns across milestones. Using data from The Generations Study, the first national probability sam- ple of White, Black, and Latinx sexual minority adults in the United States (n = 1,492), we examined variability in milestone timing and patterning using a latent profile analysis approach. We identified four distinct profiles, characterized by variability in milestone mean ages, pacing, and sequences: an early adolescence profile (22.9%), a middle adolescence profile (33.6%), a late adolescence profile (27.6%), and an adulthood profile (15.9%). Profiles were demographically distinct, varying by birth cohort, sex- ual identity, race/ethnicity, gender identity, and childhood gender nonconformity. Results suggest devel- opmental and demographic diversity in the emergence of sexual identity development across the life course, with implications for sexual minority health and thriving.
