Keep the category of sex a mandatory question in the 2021 Census.

Data collection disaggregated by sex gives us vital information for policy making and distribution of resources.

This will render useless equal opportunities monitoring designed to combat sex discrimination. It will influence governments worldwide making difficult the monitoring of imbalances resulting from sex-selective abortion, female infanticide and unequal treatment of girls and women.
