Countering previous studies that found little difference between kids of same sex couples and those in a traditional marriage, a new report reveals that children of gay parents are 35 percent less likely to make normal progress in school that those living with their own married parents.

Based on the largest sample to date for such a study, the new work from three economists raises anew the impact state laws approving of same sex marriage have on children.

The new study provided to Secrets said: "Children of same sex couples are significantly less likely to make normal progress through school than other children: 35% less likely than the children of heterosexual married parents, 23% less likely than the children of never married mothers, and 15% less likely than the children of cohabiting parents."

The study also looked at similar scholarly work that had determined no difference in children of same sex and traditional marriages. The authors said that those studies filtered the sample of children to get their result.
