Some believe that open relationships occur more frequently in certain demographics, such as the young rather than the old in America, including, more specifically, the college-educated middle-class, rather than the uneducated working-class, or people of certain ethnic and/or other racial minorities. Open relationships may also be more common among females rather than males, especially those in the same categories, such as college-educated, middle-class, white, younger Americans. This may be because women have more to gain by stressing this idea of equal rights, and that the women's rights movement supports the idea of open relationships.
