The Washington Post reports:
Children of same-sex couples perform better in school than kids raised by a mom and a dad, according to new research from several European economists. The researchers found that children raised by same-sex couples had higher test scores in elementary and secondary school and were about 7 percent more likely to graduate from high school than children raised by different-sex couples.
What’s unique about this latest research is that it follows all children born in the Netherlands from 1995 to 2005 through primary school (and beyond). The data includes information about the child’s educational performance as well as data on the child’s parents and family income. Prior studies of the children of gay and lesbian parents have often had a small sample size, of only a few dozen kids, or have used U.S. Census Bureau data, which is only a one-time snapshot.
