3. What is your sex?

Why we ask this question

Your answer is key to understanding trends in the population. It helps your local community by allowing charities, organisations, and local and central government to understand what services people might need.

This information helps monitor equality between groups of people of different sexes in your local area. Your answer will help public bodies to identify discrimination or social exclusion based on sex and work to stop it from happening.

The census first asked this question in 1801.

This question is vital for understanding population growth and equality monitoring. Please select either "Female" or "Male".

If you are considering how to answer, use the sex recorded on your birth certificate or Gender Recognition Certificate.

If you are aged 16 or over, there is a later voluntary question on gender identity. This asks if the gender you identify with is different from your sex registered at birth. If it is different, you can then record your gender identity.

Important information:

Answering on behalf of someone else

If you're answering for someone else, where possible you should ask them how they would answer. If they're away, select the answer you think they would give.
