Canada last year became the 10th country to allow residents to choose a gender option other than male or female on their passports, but most Americans agree with the Trump administration’s current consideration of limiting the definition of gender strictly to biology and oppose a third gender option on legal documents in this country.

A new Rasmussen Reports national telephone and online survey finds that 50% of American Adults oppose allowing a third gender option on passports, drivers’ licenses and other official forms of identification. Thirty-one percent (31%) favor a third gender option, but 19% are undecided. (To see survey question wording, click here.)
