This study compared how gay, lesbian, and heterosexual married couples (ns = 95, 61, and 145, respectively) allocated household labor. Partners in each couple lived together without children. Compared to both married and gay couples, lesbian couples tended to share tasks. Compared to lesbian couples, gay couples and married couples were likely to have one or the other partner perform the tasks; in married couples, this was most likely the wife. Compared to married couples, gay couples and lesbian couples were likely to split tasks so that each partner performed an equal number of different tasks. The relation between the extent to which household tasks were performed and personal power, gender role orientation, relationship satisfaction, and psychological symptoms generally varied by partner and type of couple. It is concluded that although gender is a powerful determinant of how household labor gets allocated in heterosexual married couples, no single variable carries as much weight with gay or lesbian couples.
