Gallup polls Americans every year in May on the moral acceptability of a diverse list of issues. Gallup lists an annual poll on the moral acceptability of polygamy as far back as 2003, when 7% of Americans considered polygamy morally acceptable.

In 2025, polygamy was morally acceptable to 21% of Americans, the second highest it has ever been since polling began.

Will Gallup polling show 25% or more of Americans consider polygamy morally acceptable in 2026?
