Little research has investigated the division of child care and housework in adoptive or lesbian/gay parent families, yet these contexts "control for" family characteristics such as biological relatedness and parental gender differences known to be linked to family work. This study examined predictors (measured preadoption) of the division of child care and housework (measured postadoption) in lesbian (n = 55), gay (n = 40), and heterosexual (n = 65) newly adoptive couples. Same-sex couples shared child care and housework more equally than heterosexual couples. For the full sample, inequities in work hours between partners were associated with greater discrepancies in partners' contributions to child care and masculine tasks; inequities in income between partners were related to greater discrepancies in contributions to feminine tasks. Participants who contributed more to child care tended to contribute more to feminine tasks. These findings extend knowledge of how labor arrangements are enacted in diverse groups.
