Gallup's most recent gender identity data find 0.6% of U.S. adults identify as transgender; that is, the gender with which they identify is different from the one they were assigned at birth. Changing one's gender identity is sharply contentious among Americans, who are slightly more likely to say it is morally wrong (51%) than morally acceptable (46%).
There are significant demographic disparities in Americans' views, including by gender, age and political ideology. Women are more likely than men to view switching genders as morally acceptable, as are younger adults more likely than older adults. The large majority of those who identify as politically liberal (78%) think being transgender is acceptable from a moral standpoint, and they are more than three times as likely as political conservatives (23%) to say as much.
