WASHINGTON (CBSDC) — A new study claims that children raised by same-sex parents are worse off than ones raised by a mother-father household.

Mark Regnerus of the University of Texas at Austin surveyed 3,000 people between the ages of 18-39. Of the 3,000, 175 people said their mother had a same-sex relationship while 73 said the same about their father.

The study – published in Social Science Research — finds that a majority of those surveyed had trouble adjusting socially and economically. In 25 of the 40 outcomes listed, there were “statistically-significant” differences between gay parents and biological parents.

“Although the findings reported herein may be explicable in part by a variety of forces uniquely problematic for child development in lesbian and gay families—including a lack of social support for parents, stress exposure resulting from persistent stigma, and modest or absent legal security for their parental and romantic relationship statuses—the empirical claim that no notable differences exist must go,” Regnerus said in the study.

Out of the people surveyed, more people raised under gay parents were arrested, have a lower level of household income and also said they were negatively impacted growing up than those under biological parents.

This latest study contradicts several previous ones stating that there was no difference in a child raised by same-sex parents than biological parents.

Regnerus made it clear in the study that he is not saying gay parents are worse than biological parents.

“While it is certainly accurate to affirm that sexual orientation or parental sexual behavior need have nothing to do with the ability to be a good, effective parent, the data evaluated herein using population-based estimates drawn from a large, nationally-representative sample of young Americans suggest that it may affect the reality of family experiences among a significant number.”
