The term “open marriage” was popularized in 1972 by George and Nena O’Neill’s book of the same title. Defined as a practice or a lifestyle choice in which couples engage in casual or sexual relationships with other people, open relationships continue to raise eyebrows for not being morally upright and ruining the matrimony of traditional marital relationships and family structure.
Open marriage or relationship is a complex subject, and different studies show mixed findings. In this article, we will not only look into open marriage statistics but also include unmarried couples engaged in consensual nonmonogamous lifestyle. The following statistics aim to reveal the general attitude on the subject of consensual monogamy, the demographics of individuals who engage in open relationships, and how this lifestyle affects their primary relationships as well as the individuals themselves.
Due to the vast differences in cultural views on consensual nonmonogamy, we will only focus on studies in which samples are from within the United States. We, however, will limit the information to the open and partial nonmonogamy structure and avoid one-sided monogamy as its descriptions mainly fall under infidelity. Furthermore, due to little resources or lack thereof, we will not touch on the divorce statistics in open marriages as well as how it affects the family dynamics when there are children.

Americans on Open Marriage/Relationship
American society as a whole is not at all new to the concept of open marriage or relationships. The practice of swinging can be traced as far back as the sexual revolution in the 1960s. Meanwhile, polyamory has been brushed under the rug as a lifestyle choice for the wealthy liberals for many years. However, studies show that the practice of open relationships is not exclusive to the rich and famous and is more widespread.

In a different study involving 1,658 online participants, an open relationship falls under the “consensual nonmonogamy” (CNM) type of relationship structure. In this study, open relationships are identified as having low interest in monogamy and high levels of mutual consent to the relationship structure. This study also further supports previous findings that non-heterosexual individuals are more open to consensual nonmonogamy.

Open Relationship and Social Acceptance
To sum it up, the general perception of open relationships remains divided. However, it has come a long way from being seen as downright immoral to somewhat socially acceptable. Open marriage or relationship is becoming more mainstream as couples embrace a more liberal and diversified relationship structure. We are seeing more representation of open relationships in popular culture. For instance, even online dating sites have an open relationship option, making consensual nonmonogamy a significant part of online dating statistics. Although it is still a lifestyle open to judgment and criticism, it all boils down to the couple involved. In short, it is the couple who will decide how they will navigate the open relationship structure. Lastly, it is also up to the couple to figure out how to deal with its possible effects not only on their relationship but their family as a whole.
