Sexual and gender minorities (SGM) comprise individuals whose sexual identity, sexual orientation, sexual behavior, or gender identity differ from the majority of the surrounding society. Sexual minorities include lesbians, gay men, bisexual people, asexual people, and other non-heterosexual people, Gender minorities include transgender people, non-binary (including third gender), and intersex individuals. Gender, sexual and romantic minorities (GSRM) includes individuals of a minority romantic orientation such as aromanticism.
Sexual and gender minorities includes LGBTQ people as well as those who do not identify as LGBTQ. In 2015, the United States National Institutes of Health described SGM as an "umbrella term that encompasses populations included in the acronym "LGBTI" (lesbian, gay, bisexual, transgender and intersex), and those whose sexual orientation or gender identity varies. It includes those who may not self-identify as LGBTI (e.g., queer, questioning, two-spirit, asexual, men who have sex with men, women who have sex with women, gender variant), or those who have a specific medical condition affecting reproductive development (e.g., individuals with differences or disorders of sex development, who sometimes identify as intersex)."
