I know that many Mumsnetters are concerned about changes to the status of women and girls, including collecting data about sex in the census - which is vital for equality monitoring.
There's a petition to the government at the moment.
petition.parliament.uk/petitions/202435
Keep the category of sex a mandatory question in the 2021 Census.
We oppose the published tentative recommendation by the Office of National Statistics to make sex a non-mandatory field in the 2021 Census. We demand that sex remains a mandatory question in the Census and is included in all government demographic data collection in accordance with SDG5 commitments.

Data collection disaggregated by sex gives us vital information for policy making and distribution of resources. If implemented, the ONS recommendation will make widely acceptable that sex becomes a voluntary question. 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.
