Ambigender

Ambigender is a static bigender identity in which two genders are experienced simultaneously with no fluidity or shifting. In addition to being a type of bigender identity, ambigender also falls under the multigender umbrella term.

Just like any other gender identity, ambigender people can use any set of pronouns they like, or even use multiple sets of pronouns.

In the 2020 Gender Census, 4 respondents were ambigender.

History
The term "ambigender" as a gender identity dates back at least to the mid-1990s; for example in 1993, it was mentioned in a list of terms in Cross-Talk, a transgender community magazine.

In a 2010 encyclopedia, ambigender is listed as a type of "androgyne" gender. "Androgyne identities include pangender, bigender, ambigender, nongendered, agender, gender fluid, or intergender."
