US study: children change work-sharing arrangements less in same-sex couples than in heterosexual couples

A comprehensive US-based study by Emily Curran, a sociologist at the University of Pennsylvania, compares how the birth of a child affects the distribution of paid work among heterosexual, gay and lesbian couples. The results show that gender roles and social expectations shape work division more strongly in heterosexual couples. For same-sex couples, the transition to parenthood brings surprisingly different changes.

The birth of a child brings major changes to every household, but are these changes the same across all family types? Emily Curran, a sociologist at the University of Pennsylvania, seeks to answer this question through her extensive research comparing heterosexual, gay and lesbian families in the United States.

Who stays home, who goes to work?

According to conventional wisdom, becoming parents splits couples clearly in two: one stays home more to care for the child, the other pursues their career. Yet Curran's study shows that this pattern does not apply equally to all families. The distribution of paid work depends surprisingly much on the type of couple in question.

For heterosexual couples, work-sharing arrangements undergo the greatest shift: traditional gender roles and unspoken social expectations often push couples toward typical solutions, where the woman takes on a larger share of childcare responsibilities and the man continues to work full-time. This means the daily life of heterosexual families changes more dramatically after a child is born than it does for same-sex couples.

Same-sex couples behave differently

Gay and lesbian couples distribute work responsibilities after a child's birth in markedly different ways. Because neither partner has a gender-based "expected role", they often make more conscious and equitable decisions about how to divide work. Curran's analysis emphasizes that it is precisely these invisible gender roles, rather than financial considerations or career choices, that shape how couples divide their time and responsibilities after becoming parents.

The study's findings suggest that many heterosexual couples do not actually make a conscious choice, but instead automatically follow social expectations. The experience of same-sex couples may thus offer a broader lesson on how decisions can be made differently.
