Central Survey Unit is a non-profit making survey organisation within the Northern Ireland public sector. CSU manages the fieldwork on a number of regular national surveys, such as the Labour Force Survey and the Northern Ireland Crime Survey.
The Unit conducts large scale public commissioned surveys. Recent examples include the Programme for International Student Assessment and the NI Disability Survey.
We regularly recruit Survey Interviewers to undertake surveys with members of the public on our behalf. For further information, please visit

Selected for a Survey
If you have received a letter asking you to take part in a survey, thank you for taking the time to visit our website.
Why do we need your help?
Your input is vital to the success of the survey. By taking part you can help provide an accurate picture of how changes in society, government policy, services and the economy affects you. It is important that we survey a wide cross-section of people to ensure the results accurately reflects the whole population.
Why was my address selected?
As it is impossible to survey everyone, a random sample of addresses is selected. This approach gives every address an equal chance of being selected.
We cannot substitute your address for another, as this could distort survey representativeness. We would therefore appreciate it if you could help us.
Do I have to take part?
Taking part is entirely up to you. We're just asking that you spare a little time to share your thoughts and opinions. We know your time is precious, but your input really does make a difference. With your support we can help government and charities make the right decisions about the big issues.
How was my address chosen?
Your address was selected at random from a list of all addresses in Northern Ireland.
What happens to the information I provide?
NISRA's Central Survey Unit places great emphasis on confidentiality and goes to considerable lengths to maintain such confidentiality. Any information given is strictly confidential and NISRA's Central Survey Unit will not release any information that would identify you or anyone in your household.
If you would like any more details please give us a call. (02890 255118)
