The 2017 Test is an important part of ONS's preparations for the
2021 Census. If you've been invited to take part, please fill in
your questionnaire as soon as possible.
What you need to do
If ONS needs you to take part in the test, you'll have received
a letter with a unique access code in late March. Simply head to
census.gov.uk and enter the code to access the questionnaire.
You'll then just need to answer a few questions about yourself
and the people in your household. It should only take about 10
minutes for each person.
Whatever you tell the census test will be in strictest
confidence. Your information will only be used by ONS to assess
questions and systems ahead of 2021.
If you need help
If you need any help with your census test questionnaire, call
ONS's helpline on 0300 068 3001. You can also visit census.gov.uk
to get help and fill in your questionnaire online.
Census officers will be working in South Somerset from 13 April.
They'll be visiting households that haven't responded to offer help
and encourage them to take part in the test.
Why the test matters
It's crucial ONS tests key elements to make sure everything will
work as it should on census day. By taking part in the test, you'll
help make this happen.
ONS is also testing new questions - including one on sexual
identity - to find out whether they affect people's responses.
