Homosexual or Not: Does it Matter Who Raises the Kids?

The widely circulated claim that parents engaged in same-sex relationships do just as well as other parents at raising children—a claim widely known today as the “no differences” thesis—is not settled science. Two new peer-reviewed studies released this week by the academic journal Social Science Researchchallenge the claim that there are no differences in outcomes between children raised by parents who have same-sex relationships and those raised by their biological mother and father in intact, stable marriages.

In the first article, family studies scholar Loren Marks of Louisiana State University reviews the 59 studies that are referenced in the 2005 American Psychological Association brief that came to the conclusion that there are “no differences.” Marks concludes that “not one of the 59 studies referenced … 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. The available data, which are drawn primarily from small convenience samples, are insufficient to support a strong generalizable claim either way.”[1] Marks’s study casts significant doubt upon the older evidence on which the APA brief, and thus the “no differences” paradigm, rests.

The second article, by sociologist Mark Regnerus of the University of Texas at Austin, presents new and extensive empirical evidence that shows there are differences in outcomes between the children of a parent who has same-sex relationships and children raised by their married, biological mother and father. This new evidence was gathered by Dr. Regnerus, the lead investigator of the New Family Structures Study (NFSS) of the University of Texas,which in 2011 surveyed 2,988 young adults for the specific purpose of collecting more reliable, nationally representative data about children from various family origins. (The Witherspoon Institute provided funding for this study.) Already, the NFSS has been acknowledged by critics to be “better situated than virtually all previous studies to detect differences between these groups in the population.”[2]

As Regnerus explains, the NFSS is unique among gay parenting research in three ways:

First, it compares the outcomes of children who reported having a mother who had a same-sex relationship with another woman (LM for short) or a father who had a same-sex relationship with another man (GF for short) with the outcomes of children who reported coming from an intact biological family (IBF for short). Most gay parenting research compares gay and lesbian parenting to single, divorced, and step-parent parenting, or conversely compares a select, and often socio-economically privileged, population of gay parents to a broad, representative sample of the general population.

Second, the NFSS gathered responses from young adult children. Other gay parenting studies focus on the responses of parents for their views about what it is like to be parenting as a gay man or lesbian woman. The NFSS interviewed the sons and daughters of GFs and LMs after they had grown up and matured into young adults (ages 18-39). This allowed the children to speak for themselves about their past experiences and to report on how they are doing at present.

Finally, the NFSS drew from a large, random sample of the U.S. population. To date, there is only one other gay parenting study that draws from a large, random sample, that of Michael Rosenfeld of Stanford University, who relies upon 2010 U.S. Census data. Every other gay parenting study thus far relies upon small or non-probability samples, which are inadequate for drawing conclusions about the population at large. Additionally, the NFSS gathered more data of interest to gay parenting researchers than did the U.S. Census, soliciting answers on a wide range of outcomes, including social, emotional, and relational well-being.

Qualifications of the Results

Before detailing the results of the NFSS, two important points must be made: First, the results do not claim to establish causality between parenting and child outcomes. In other words, the results are not a “report card” on gay parenting, but a report on the average condition of grown children from households of gay and lesbian parents versus those from IBFs. So, for instance, when the study finds that children who have had a parent in a same-sex romantic relationship are much more likely to suffer from depression as young adults than the children who come from IBFs, this doesnot claim that the gay parent was the cause of the depression in his or her child; simply that such children on average have more depression, for reasons unidentified by the study. That said, however, the study controlled for variables like age, gender, race, level of mother’s education, perceived household income while growing up, the degree of legislative gay-friendliness of the respondent’s home state, and experience of being bullied as a youth. Controls help eliminate alternative explanations for a given outcome, making the causal link between parenting structure and children’s outcomes more likely when the results are statistically significant after controls.

Second, the kind of gay parenting identified was rarely planned by two gay parents. The study found that the children who were raised by a gay or lesbian parent as little as 15 years ago were usually conceived within a heterosexual marriage, which then underwent divorce or separation, leaving the child with a single parent. That parent then had at least one same-sex romantic relationship, sometimes outside of the child’s home, sometimes within it. To be more specific, among the respondents who said their mother had a same-sex romantic relationship, a minority, 23%, said they had spent at least three years living in the same household with both their mother and her romantic partner. Only 2 out of the 15,000 screened spent a span of 18 years with the same two mothers. Among those who said their father had had a same-sex relationship, 1.1% of children reported spending at least three years together with both men.

This strongly suggests that the parents’ same-sex relationships were often short-lived, a finding consistent with the broader research on elevated levels of instability among same-sex romantic partners. For example, a recent 2012 study of same-sex couples in Great Britain finds that gay and lesbian cohabiting couples are more likely to separate than heterosexual couples.[3] A 2006 study of same sex marriages in Norway and Sweden found that “divorce risk levels are considerably higher in same-sex marriages”[4] such that Swedish lesbian couples are more than three times as likely to divorce as heterosexual couples, and Swedish gay couples are 1.35 times more likely to divorce (net of controls). Timothy Biblarz and Judith Stacey, two of the most outspoken advocates for same-sex marriage in the U.S. academy, acknowledge that there is more instability among lesbian parents.[5]

Therefore, while critics of the NFSS have faulted it for lacking comparisons between children of IBFs and the children of committed and intact gay or lesbian couples, this was attempted, but was not feasible. Despite drawing from a large, representative sample of the U.S. population, and despite using screening tactics designed to boost the number of respondents who reported having had a parent in a same-sex relationship, a very small segment reported having been parented by the same two women or two men for a minimum of three years. Although there is much speculation that today there are large numbers of same-sex couples in the U.S. who are providing a stable, long-term parenting relationship for their children, no studies based upon large, random samples of the U.S. population have been published that show this to be true, and the above-cited studies of different nations show that on average, same-sex couple relationships are more short-lived than those of opposite-sex couples.

Despite the lack of empirical evidence for the claim that today there are large numbers of stable, two-parent gay households, for the last ten years, contemporary gay parenting research has nevertheless claimed that there are “no significant differences” (and some benefits) to being raised by same-sex parents. Therefore, Regnerus analyzed the new NFSS data to verify this claim. In the end, he found the claim to be more plausible when comparing the grown children of parents who had a same-sex relationship to the grown children of divorced, adopted, single-parented, or step-parented arrangements. The claim is false if one compares the grown children of a parent who had a same-sex relationship to those from IBFs. While the study has been criticized for “comparing apples to oranges,” Regnerus’s work studies the reality of the population of children who were raised by parents who had same-sex relationships. As the next sections show, there are clear and, in most cases, very unfortunate differences between the children of parents who had a same-sex relationship and those from biological families of still-married parents.

The following selection of NFSS outcomes can be found animated, graphed, and numerically compared at: www.familystructurestudies.com.

Social Outcomes

Public perceptions and stereotypes of children of gays and lesbians usually assume them to be white, upper-middle-class members of society. However, in response to questions about race, 48% of the respondents with a GF, and 43% of the respondents with an LM indicated that they were either black or Hispanic, a number much higher than previously found by studies based on convenience samples.[6] On economic outcomes, grown children of an LM were almost four times more likely to be currently on public assistance than the grown children of IBFs. As young adults, they were also 3.5 times more likely to be unemployed than the grown children of IBFs.

On criminal outcomes, the children of GFs showed the greatest propensity to be involved in crime. They were, on average, more frequently arrested and pled guilty to more non-minor offenses than the young-adult children in any other category. The children of LMs reported the second highest frequency of involvement in crimes and arrests, and in both categories the young-adult children of intact biological families reported the lowest frequency of involvement in crimes or arrests.

Contrary to recent and widely circulated reports that there is no sexual victimization in lesbian households, the NFSS found that, when asked if they were ever touched sexually by a parent or other adult, the children of LMs were eleven times more likely to say “yes” than the children from an IBF, and the children of GFs were three times more likely to say “yes.” The children of IBFs were the least likely of all family types to have ever been touched sexually: only 2% reported affirmatively (compared to 23% of LMs who replied “yes”). When asked if they were ever forced to have sex against their will, the children of LMs were the worst off again—four times more likely to say “yes” than the children of IBFs. The children of GFs were three times more likely to have been forced to have sex than the children of IBFs. In percentages, 31% of LMs said they had been forced to have sex, compared with 25% of GFs and 8% of IBFs. These results are generally consistent with research on heterosexual families. For instance, a recent federal report showed that children in heterosexual families are least likely to be sexually, physically, or emotionally abused in an intact, biological, married family.[7]

Regarding physical health, when asked if they had ever had a sexually transmitted infection (STI), the young-adult children of GFs were three times more likely to say “yes” than those of IBFs. Children of LMs were two and a half times more likely to say “yes,” followed by the children of stepfamilies, who were twice as likely to have had an STI as children of IBFs. Children of IBFs and children from “other” family types were the least likely of all to have had an STI. When asked to report upon frequency of marijuana use, the young-adult children of divorced parents were the worst off, reporting that they had used marijuana on average one and a half times more frequently than children of IBFs; next came the children of LMs, followed by the children of single parents, and the children of GFs. The children adopted prior to age 2 by strangers (people unrelated to them) and the children of IBFs reported least frequent marijuana use as young adults.

Emotional and Mental Health Outcomes

Respondents were asked to report their sentiment about their family experiences while growing up. The children of LMs reported the lowest levels of perceived safety in their childhood home, followed by children of GFs, with the children of IBFs reporting the highest levels of perceived safety. When asked if they were recently or currently in therapy “for a problem connected with anxiety, depression, relationships, etc.,” children adopted by strangers reported receiving such therapy the mostfollowed by the children of LMs. The children from IBFs were least likely to report receiving therapy.

On the CES-D depression index, an eight-measure survey of respondents’ happy-to-depressed thoughts over the previous seven days, the young-adult children of LMs and GFs reported statistically significantly higher levels of depression than young-adult children from IBFs. The young-adult children of GFs were twice as more likely to have thought about suicide in the previous 12 months as the children of LMs, and almost five times more likely than the children of IBFs to have thought about the same.

Relational Outcomes

The study asked questions about the history and current status of the young adults’ relationships. When asked to rate the quality of their current relationship, the children of GFs reported the lowest, followed by children adopted by strangers, the children of stepfamilies, and then the children of LMs.

When asked about the number of times they thought that their current relationship was in trouble, the children of GFs reported the highest numbers again, followed by the children of divorced parents. The children of IBFs reported both the highest levels of relationship quality and the lowest frequency of thinking their relationship to be in trouble of all of the family arrangements.

When asked about infidelity, children of LMs were three times more likely to report having had had an affair while married/cohabiting than children of IBFs, followed by children from stepfamilies (who were two and a half times more likely than IBFs) and children of GFs (who were twice as likely).

The NFSS asked respondents to identify their sexual orientation and found that children of LMs were more open to same-sex romantic relationships, bisexuality, and asexuality than any other group. Daughters of LMs reported an average of just over one female sex partner and four male sex partners in their lifetimes, in contrast to daughters of IBFs who reported an average of only 0.22 female sex partners and 2.79 male sex partners in their lifetimes. Daughters of LMs were also most likely to self-report asexuality, “not sexually attracted to either males or females” (4.1% of females from lesbian mothers compared to 0.5% of females from IBFs). Children of GFs were the next least likely to identify as fully heterosexual. Children from IBFs were most likely of all family types to identify as entirely heterosexual.


Taken together, the findings of the NFSS disprove the claim that there are no differences between children raised by parents who have same-sex relationships and children raised in intact, biological, married families when it comes to the social, emotional, and relational outcomes of their children. On 25 out of 40 outcomes evaluated by Regnerus, there were statistically significant differences between children from IBFs and those of LMs in many areas that are unambiguously suboptimal. On 11 out of 40 outcomes, there were statistically significant differences between children from IBFs and those who reported having a GF in many areas that are suboptimal. The “no differences” claim is therefore unsound and ought to be replaced by an acknowledgement of difference.

Acknowledging the differences between the children of IBFs and those from LMs and GFs better accords with the established body of social science over the last 25 years, which finds that children do best when they are raised by their married, biological mother and father. At the turn of the millennium, social scientists widely agreed that children raised by unmarried mothers, divorced parents, cohabiting parents, and step-parents fared worse than children raised by their still-married, biological parents.[8] Although data on gay and lesbian parenting were not yet available at that time, it was difficult to imagine that gay and lesbian parents would be able to accomplish what parents in step-parenting, adoptive, single-parenting, and cohabiting contexts had not been able to do, namely, replicate the optimal child-rearing environment of married, biological-parent homes.

However, as early as 2001, social scientists working on sexual orientation and parenting began to claim just that, that there were not as many differences as sociologists would expect between outcomes for children in same-sex versus heterosexual unions, and that the differences were not negative, but favorable.[9] Since then, an increase in gay parenting research over the last decade has made similar claims, such that the emergent message from social scientists working in gay parenting has gone in a different direction, alleging that there are no differences in outcomes—and some advantages—for children raised by parents with same-sex behavior.[10]

By challenging these claims, the Regnerus and Marks papers are consistent with the social science consensus that existed at the turn of the millennium: to be raised in an intact biological family presents clear advantages for children over other forms of parenting. In particular, the NFSS provides evidence that previous generations of social scientists were unable to gather: that children from intact, biological families also out-perform peers who were raised in homes of a parent who had same-sex relationships. Therefore, these two new studies reaffirm—and strengthen—the conviction that the gold standard for raising children is still the intact, biological family.[11]

    Thank you for providing a logic based argument against the common, unsubstantiated view so widely distributed.  To paraphrase GK Chesterton, “We don’t know what we are doing, because we don’t know what we are UNdoing.”

       I’ve been waiting for this for a long time, a clear and concise argument against the benefits of homosexual adoption based on empircal evidence!  A big thank you to Ana for bringing this to the front and center on this matter. 

       In a world of sound bites and emotional pseudo profundities, the reality and truth are easily hidden away.  Something as obviously wrong (even without research) as same sex parenting becomes acceptable and difficult to defend against when people are swayed by pure emotion. 

       The evidence presented here should be at the core of the argument going forward in each and every state battle on same sex adoption. 

  • Masfrazier

    Wow. That is amazing how you post all of that research and just bank on people not noticing that most surveyed GF and LM families were resultant of divorce and that you compare them with IBFs. Why not compare the slums of russia and china to wallstreet and analyze how nationality affects economic success?

  • Annie

    That is a great deal of information, but the studies have just started. I think the fact that someone is adopted in the first place means their biological parents gave them away. That would be enough to damage myself worth and possibly lead me into many of the statistic you reported.

    At least these homosexual couple are adopting these children, most likely giving them some sort of family rather than leaving them in foster care. I don’t see you comparing children who are adopted by homosexual couples compared to children who are never adopted at all..

    I agree there is a difference between gay/lesbian couples as parents and IBFs but there are major differences between IBF and other IBFs due to culture, religion, economic status. Out of my graduating 8th grade class from a Catholic school, 6 students from strong IBF families where the parents were very close and went to church every Sunday or everyday together, all 6 ended up in terrible situations as teenagers and young adults.One was pregnant in high school, one was caught selling drugs, one was anorexic weighing 65 lbs. at 5’5 at 21 yrs.old. and two were severe drugs addicts. Those were just the obvious ones.

    These studies are just beginning and it is way too early to come out with any clear assessment. I am sure there will be a great deal more research, but I don’t think we will ever have a clear answer.

  • Rickeileen

    Masfrazier – I think you missed the “Qualification of the Results” section where the author directly talks to that point.

  • Davy, I don’t think we read the same article. You are using a great deal of confirmation bias so you can justify enforcing your Christian lifestyle on others. Mark Regnerus has terrible research methodology and many of his questions specifically target moderate and liberal concepts as negatives, showing an almost reactionary bias.
