Gender is a multi-faceted social system generally based on the norms, behaviors, and societal roles expected of individuals based primarily on the binary sex they were determined to be at birth, based on the appearance of their external genitalia.
Gender identity describes a person’s self-perceived gender. Gender expression is how a person presents or conveys their gender to the world. Gender roles are the societal expectations of how people should act, speak, dress, groom, and conduct themselves based on their assigned sex.
