This paper critically reviews research on sexual and gender minority (SGM) families, including lesbian, gay, bisexual, transgender, queer, asexual, intersex, and other (LGBTQAI+) families, in the past decade (2010–2020). First, this paper details the three primary subareas that make up the majority of research on SGM families: (1) SGM family of origin relationships, (2) SGM intimate relationships, and (3) SGM‐parent families. Next, this paper highlights three main gaps in this decade's research: (1) a focus on gay, lesbian, and same‐sex families (and to a lesser extent bisexual and transgender families) and a lack of attention to the diverse family ties of single SGM people as well as intersex, asexual, queer, gender non‐binary/non‐conforming, polyamorous, and other SGM families; (2) an emphasis on white, socioeconomically advantaged SGM people and a failure to account for the significant racial‐ethnic and socioeconomic diversity in the SGM population; and (3) a lack of integration of SGM experiences across the life course, from childhood to old age. Future research should refine the measurement and analysis of SGM family ties with novel theory and data across the methodological spectrum.
