Only a tiny minority of human beings are transgender. Even in cultures where the concept of a third gender is celebrated, it is a rare phenomenon.

Canada is the first country to provide census data on transgender and non-binary people: "Of the nearly 30.5 million people in Canada aged 15 and older living in a private household in May 2021, 100,815 were transgender (59,460) or non-binary (41,355), accounting for 0.33% of the population in this age group."
