Marriage and Family researcher, Mark Regnerus (University of Texas at Austin, senior fellow at the Austin Institute for the Study of Family and Culture) points to a new Canadian study published in the journal, Review of the Economics of the Household (click for abstract) that shows the advantages to children raised by a married mother and father as compared to children raised in other family arrangements including same sex households.
…children of gay and lesbian couples are only about 65 percent as likely to have graduated from high school as the children of married, opposite-sex couples. And gender matters, too: girls are more apt to struggle than boys, with daughters of gay parents displaying dramatically low graduation rates.
Unlike US-based studies, this one evaluates a 20 percent sample of the Canadian census, where same-sex couples have had access to all taxation and government benefits since 1997 and to marriage since 2005.…children of married opposite-sex families have a high graduation rate compared to the others; children of lesbian families have a very low graduation rate compared to the others; and the other four types [common law, gay, single mother, single father] are similar to each other and lie in between the married/lesbian extremes.
…the particular gender mix of a same-sex household has a dramatic difference in the association with child graduation. Consider the case of girls…. Regardless of the controls and whether or not girls are currently living in a gay or lesbian household, the odds of graduating from high school are considerably lower than any other household type. Indeed, girls living in gay households are only 15 percent as likely to graduate compared to girls from opposite sex married homes.
