What is the purpose of the census?
The census is a once-in-a-decade survey that gives us the most accurate estimate of all the people and households in England and Wales.
It has been carried out every decade since 1801, with the exception of 1941.
The census is important as it will ensure everyone from local government to charities can put services and funding in the places where they are most needed, like hospitals, schools, and new roads. The census includes questions about your sex, age, work, health, education, household size and ethnicity.
When will the next census occur?
The next census will take place on 21 March 2021.
How to complete your census questionnaire
It will be the first census to be run mainly online. Households will receive a letter with a unique access code. This code will allow you to complete the questionnaire on your computer, phone or tablet. There will be help and paper questionnaires for those that need them.
There are new questions for armed forces veterans, as well as voluntary questions for those aged 16 and over on sexual orientation and gender identity.
Results will be available within 12 months.
Personal records will however be locked away for a 100 years and kept safe for future generations.
More information about the census can be found on the Census 2021 website.
