Gays and Lesbians Have Different Reasons to Get Married

Same-sex marriage is now legal across the United States, but research on the reasons gays and lesbians get married is sparse. Now, in a recent study published in the journal Demography, a team of researchers looked at earnings and parenting patterns over time among married Swedish couples and found that registered partnership is important to both—but for different reasons.

The researchers looked at and followed Swedish couples who entered into registered partnerships sometime between 1995—the year Sweden approved registered partnerships of same-sex couples—through 2007. (They also analyzed data from 1994 to get a glimpse of life before official partnership.) The 1,381 couples in the study—672 lesbian and 709 gay couples—were entering their first unions and were between the ages of 20 and 64. The authors analyzed demographic data—including annual earnings from the couples, the differences between the earnings of people in the couple and the number of children in each union—for same-sex couples and compared the results to 267,264 heterosexual couples.

Sweden provides an intriguing opportunity to study how policy impacts same-sex marriages; though the country approved registered partnerships of same-sex couples in 1995, it wasn’t until a 2002 law that the country’s registered partners were allowed to jointly adopt children. (Swedish law dictates that married couples can only adopt jointly, thereby making it impossible for one partner to adopt without the other if the two partners are married.)

The authors found that gays and lesbians got married for very different reasons. Most gay couples entered their union without kids, and that number remained close to zero after marriage; the authors concluded that “the main function of registered partnership for gays is resource pooling,” they write in the paper. “For lesbians, on the other hand, the right to joint or step-parent adoption allowed in 2002 raised fertility and possibly entry into partnership.”

In other words, gay couples were more likely to get married to combine incomes and resources; lesbians tended to use marriage as a stepping stool towards creating a family, further emphasized by a spike in lesbians registering for marriage in 2002, the year when joint adoption was made legal.

The decision to have children is likely a large factor responsible for these differences, said Lena Edlund, an associate professor at Columbia University and one of the economists involved with the study. “I think the asymmetry results from a much greater difficulty male couples have in finding children that they can parent jointly,” she said in an e-mail. “It is also possible that male couples have a lower desire for joint children.”
