Census day is 21 March 2021

What is the census?

The census is a national survey that happens every ten years and provides a picture of all the people and households in England and Wales. 

The answers given by householders to the census questions will help organisations, including Three Rivers District Council, make decisions on planning and funding public services in their local area. 

What do I need to do?

Households will begin receiving letters with online codes in March explaining how they can complete their online census. People can also request a paper questionnaire if they’d prefer to complete the census that way.  

Every household should complete the census on Sunday 21 March 2021 or as soon as possible after.

The census should take about ten minutes for the household questions and ten minutes per person.

Everyone in England and Wales is legally required to complete a census or be included on a census for the place where they’re living or staying.

Every householder at an address is responsible for completing a census questionnaire for their household. The householder should either answer the individual questions for all household members or make sure each member answers their own.
