Sex

The ‘Sex’ variable in the 2021 Census is based on a person’s sex characteristics, such as their chromosomes, hormones and reproductive organs (ABS 2022b). While typically based upon the sex characteristics observed and recorded at birth or infancy, a person's sex can change over the course of their lifetime and may differ from their sex recorded at birth (AIHW 2022).
