In a historic study of children raised by homosexual parents, sociologist Mark Regnerus of the University of Texas at Austin has overturned the conventional academic wisdom that such children suffer no disadvantages when compared to children raised by their married mother and father. Just published in the journal Social Science Research,[1] the most careful, rigorous, and methodologically sound study ever conducted on this issue found numerous and significant differences between these groups--with the outcomes for children of homosexuals rated "suboptimal" (Regnerus' word) in almost every category.
The Debate Over Homosexual Parents
In the larger cultural, political, and legal debates over homosexuality, one significant smaller debate has been over homosexual parents. Do children who are raised by homosexual parents or caregivers suffer disadvantages in comparison to children raised in other family structures--particularly children raised by a married mother and father? This question is essential to political and ethical debates over adoption, foster care, and artificial reproductive technology, and it is highly relevant to the raging debate over same-sex "marriage." The argument that "children need a mom and a dad" is central to the defense of marriage as the union of one man and one woman.
Here is how the debate over the optimal family structure for children and the impact of homosexual parents has usually gone:
- Pro-family organizations (like Family Research Council) assert, "Social science research shows that children do best when raised by their own biological mother and father who are committed to one another in a life-long marriage." This statement is true, and rests on a large and robust collection of studies.
- Pro-homosexual activists respond, "Ah, but most of those studies compared children raised by a married couple with those raised by divorced or single parents--not with homosexual parents." (This is also true--in large part because the homosexual population, and especially the population of homosexuals raising children, is so small that it is difficult to obtain a representative sample.)
- The advocates of homosexual parenting then continue, "Research done specifically on children raised by homosexual parents shows that there are no differences (or no differences that suggest any disadvantage) between them and children raised by heterosexual parents."
- Pro-family groups respond with a number of critiques of such studies on homosexual parents. For example, such studies usually have relied on samples that are small and not representative of the population, and they frequently have been conducted by openly homosexual researchers who have an ideological bias on the question being studied. In addition, these studies also usually make comparisons with children raised by divorced or single parents--rather than with children raised by their married, biological mother and father.
In fact, an important article published in tandem with the Regnerus study (by Loren Marks, Louisiana State University) analyzes the 59 previous studies cited in a 2005 policy brief on homosexual parents by the American Psychological Association (APA).[2] Marks debunks the APA's claim that "[n]ot a single study has found children of lesbian or gay parents to be disadvantaged in any significant respect relative to children of heterosexual parents." Marks also points out that only four of the 59 studies cited by the APA even met the APA's own standards by "provid[ing] evidence of statistical power." As Marks so carefully documents, "[N]ot one of the 59 studies referenced in the 2005 APA Brief compares a large, random, representative sample of lesbian or gay parents and their children with a large, random, representative sample of married parents and their children."
To summarize, we have been left with large, scientifically strong studies showing children do best with their married mother and father--but which do not make comparisons with homosexual parents or couples; and studies which purportedly show that children of homosexuals do just as well as other children--but which are methodologically weak and thus scientifically inconclusive.
What the Study Found
The study looked at 40 different outcomes, but reported data for children with "lesbian mothers" and those with "gay fathers" separately. Therefore, there actually were 80 outcome measures that could be said to compare children with "homosexual parents" to those from other family structures. When compared with outcomes for children raised by an "intact biological family" (with a married, biological mother and father), the children of homosexuals did worse (or, in the case of their own sexual orientation, were more likely to deviate from the societal norm) on 77 out of 80 outcome measures.(The only exceptions: children of "gay fathers" were more likely to vote; children of lesbians used alcohol less frequently; and children of "gay fathers" used alcohol at the same rate as those in intact biological families).
Of course, anyone who has had a college course in statistics knows that when a survey shows there are differences between two groups, it is important to test whether that finding is "statistically significant." This is because it is always possible, by chance, that a sample may not accurately reflect the overall population on a particular point. However, through statistical analysis researchers can calculate the likelihood of this, and when they have a high level of confidence that a difference identified in the survey represents an actual difference in the national population, we say that finding is "statistically significant." (This does not mean the other findings are unimportant--just that we cannot have as high a level of confidence in them.)
Regnerus has analyzed his findings, and their statistical significance, in two ways--first by a simple and direct comparison between what is reported by the children of homosexual parents and the children of "intact biological families" ("IBFs"), and second by "controlling" for a variety of other characteristics. "Controlling for income," for example, would mean showing that "IBF" children do not do better just because their married parents have higher incomes, but that they do better even when the incomes of their households and the households of homosexual parents are the same. Again, Regnerus has done these comparisons for "LMs" (children of "lesbian mothers") and "GFs" (children of gay fathers) separately.
There are eight outcome variables where differences between the children of homosexual parents and married parents were not only present, and favorable to the married parents, but where these findings were statistically significant for both children of lesbian mothers and "gay" fathers and both with and without controls. While all the findings in the study are important, these are the strongest possible ones--virtually irrefutable. Compared with children raised by their married biological parents (IBF), children of homosexual parents (LM and GF):
- Are much more likely to have received welfare (IBF 17%; LM 69%; GF 57%)
- Have lower educational attainment
- Report less safety and security in their family of origin
- Report more ongoing "negative impact" from their family of origin
- Are more likely to suffer from depression
- Have been arrested more often
- If they are female, have had more sexual partners--both male and female
The high mathematical standard of "statistical significance" was more difficult to reach for the children of "gay fathers" in this study because there were fewer of them. The following, however, are some additional areas in which the children of lesbian mothers (who represented 71% of all the children with homosexual parents in this study) differed from the IBF children, in ways that were statistically significant in both a direct comparison and with controls. Children of lesbian mothers:
- Are more likely to be currently cohabiting
- Are almost 4 times more likely to be currently on public assistance
- Are less likely to be currently employed full-time
- Are more than 3 times more likely to be unemployed
- Are nearly 4 times more likely to identify as something other than entirely heterosexual
- Are 3 times as likely to have had an affair while married or cohabiting
- Are an astonishing 10 times more likely to have been "touched sexually by a parent or other adult caregiver."
- Are nearly 4 times as likely to have been "physically forced" to have sex against their will
- Are more likely to have "attachment" problems related to the ability to depend on others
- Use marijuana more frequently
- Smoke more frequently
- Watch TV for long periods more frequently
- Have more often pled guilty to a non-minor offense
