How we will contact you

The census in Northern Ireland is governed by the Census Act (Northern Ireland) 1969. Under this Act, it is compulsory by law for every household to complete the census.

Now that Census Day has passed we are sending letters to those who have refused to make a census return. If you’ve received a letter with a warning, please fill in the questionnaire enclosed with the letter and return it to us in the return envelope. Remember that this must be completed based on your circumstances on Census Day ( Sunday 21 March 2021).


WARNING: If you do not return the enclosed questionnaire by 10 August 2021 your details will be passed to our legal team for their action which could involve preparation of a case file for use by the Public Prosecution Service. A guilty verdict will result in a criminal record and a fine of up to £1,000.

Important information:

We will not call you for information about your census, unless you've made a query or complaint.

We will never ask you for your national insurance number, passwords, bank account details, or your credit or debit card numbers.
