"The term ‘gender identity’, distinct from the term ‘sexual orientation’ refers to a person's innate, deeply felt psychological identification as a man, woman or some other gender, which may or may not correspond to the sex assigned to them at birth (e.g., the sex listed on their birth certificate).
For transgender people, gender identity may differ from physical anatomy or expected social roles. It is important to note that gender identity, biological sex, and sexual orientation are separate and that you cannot assume how someone identifies in one category based on how they identify in another category".
