Households across England and Wales will be asked to complete their Census 2021 questionnaire, which gathers vital information to help plan services such as transport, education and healthcare.

Every household will be sent a letter to their postal address with their unique access code, allowing them to complete the questionnaire on their computers, phones or tablets.

Officially it opens on Sunday 21 March, but households can complete theirs now, as long as they have received their unique access code and will be living at the same address when the Census 2021 opens.

A paper Census form can be requested from or by calling the Census Contact Centre on 0800 141 2021.
