The census, run by the Office for National Statistics, is a once-in-a-decade survey that gives the most accurate estimate of all the people and households in England and Wales.
All households will be asked to take part in Census 2021 on 21 March.
This census will be the first to be predominantly online, with households receiving a letter with a unique access code to complete the questionnaire on a computer, phone or tablet. Paper questionnaires will be available if you need them.
The census results will be available within 12 months and will inform where millions of pounds of public funding is spent on services like cycle routes, schools and surgeries.
