WASHINGTON, D.C. -- A larger majority of Americans now (69%) than in 2021 (62%) say transgender athletes should only be allowed to compete on sports teams that conform with their birth gender. Likewise, fewer endorse transgender athletes being able to play on teams that match their current gender identity, 26%, down from 34%.

The shift toward greater public opposition to transgender athletes competing on the basis of their current gender identity has occurred at the same time that more U.S. adults say they know a transgender person. Thirty-nine percent of Americans, up from 31% in 2021, say someone they know personally has told them they are transgender.
But both Americans who know and do not know a transgender individual have become less supportive of allowing transgender athletes to play on the team of their choice. Currently, 30% of those who know a transgender person favor allowing athletes to play on teams that match their current gender identity, down from 40% in 2021. Among those who do not know a transgender person, support is now 23%, down from 31%.
