California officially became the first US state to legally recognize nonbinary genders. Residents can now mark themselves as male, female, or nonbinary on all identity documents issued by the state, such as driver’s licenses, death certificates, and birth certificates. A nonbinary gender will be designated by X, male by M, and female by F.

The new Gender Recognition Act eases the requirements for changing one’s gender on official state documents. Previously, Californians who wanted to legally change their gender were required to appear in court and procure a sworn statement from a physician about the extent of the medical treatment they received during transition. This bill eliminated those requirements, and it also allows individuals under the age of 18 to apply.

While California is the first state to offer statewide recognition, other states have made strides. Back in June, Oregon’s Department of Motor Vehicles (DMV) announced that it would allow a nonbinary “X” mark on state IDs and driver’s licenses. Washington, D.C. also announced a gender-neutral “X” designation for the district’s driver’s licenses and identity cards that same month.
