[Comment] The future of survey research with the world's sexual or gender minority youth

Adolescents and young adults with diverse sexual and gender identities bear a disproportionate burden of health adversities.1 Although 90% of adolescents live in low-income and middle-income countries (LMICs), population-based health survey data among young people of a sexual or gender minority are rare in these settings.2–4 We use the term sexual or gender minority to refer to young people with diverse sexual orientations, gender identities, and gender expressions; and the term minority to signal that these populations are often underrepresented in population-based research, despite the tireless efforts of activists, scientists, and leaders to ensure the right of sexual and gender minorities to be counted.
