About 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 will be the first run predominately online, with households receiving a letter with a unique access code, allowing them to complete the questionnaire on their computers, phones or tablets.
Why do we have a census?
"A successful census will ensure everyone from local government to charities can put services and funding in the places where they are most needed," Ian Bell, deputy national statistician at the Office for National Statistics, said.
"This could mean things like doctors' surgeries, schools and new transport routes. That's why it is so important everyone takes part and we have made it easier for people to do so online on any device. with help and paper questionnaires for those that need them."
When will it happen?
Census day will be on March 2021, but households across the country will receive letters with online codes allowing them to take part from early March.
What will it include?
The census will include questions about your sex, age, work, health, education, household size and ethnicity. And, for the first time, there will be a question asking people whether they have served in the armed forces, as well as voluntary questions for those ages 16 and over on sexual orientation and gender identity.
When are the results published?
Results will be available within 12 months, although personal records will be locked away for 100 years, kept safe for future generations.
