About One in Five Americans Now Find Polygamy or Polyamory Acceptable, Data Analyst Says

Key points: Data analyst Harry Enten reported a jump in U.S. acceptance of polygamy and polyamory from about 6% two decades ago to roughly 21% today. The discussion followed a papal statement emphasizing one spouse is sufficient amid concerns about polygamy in parts of Africa. Younger Americans show higher support, estimates suggest around 9 million people are in polyamorous relationships, and online interest is highest in Alaska and Oregon.

Journalist Erin Burnett said she was surprised after data analyst Harry Enten reported a notable rise in U.S. acceptance of polygamy and polyamorous relationships.

The exchange took place on the news program OutFront following a recent papal statement urging Catholics that one spouse is sufficient — a response that came amid concerns from some African bishops about the rise of polygamy in parts of their regions.

Attitudes Shifting

Enten cautioned that it is difficult to build a precise trend line for how many Americans are currently in polyamorous relationships versus 20 years ago. Still, he emphasized a clear change in attitudes: roughly 6% of Americans said polygamy was morally acceptable two decades ago, while today that share is about 21%.

"Wait. Can I just say something? That’s one in five people," Burnett reacted on air.

Enten added that support is stronger among younger cohorts and that although exact counts are hard to verify, estimates place about 9 million people in the U.S. in polyamorous relationships. He also noted that online interest and searches for polyamory are highest in Alaska and Oregon — not the more religious states some might assume.

"You might think of Utah and Mormon communities, but the states that search for polyamorous relationships the most are actually Alaska and Oregon," Enten said.

The pair exchanged lighthearted comments about the imagery used to illustrate the topic — photos often show hands layered together rather than faces — and Enten quipped, "Yeah, monogamy for me. Thank you." Burnett responded, "That really has you thinking."

Context and Caveats

These figures reflect changes in public opinion, not legal recognition. Polygamy and multiple-spouse marriages remain largely prohibited under U.S. law, and survey results measure attitudes rather than the legal status or precise number of participants. As Enten noted, young people today tend to express more openness to non-monogamous arrangements.
