Received a letter?
One of our interviewers will call at your house in the next couple of weeks, to explain more about the study. The interviewer will show an official identification card with their name, photograph and the NISRA logo. The interviewer will be happy to arrange a convenient time to conduct the interview if you are busy at the first call.

The sample for the Omnibus survey consists of a systematic random sample of addresses selected from the Pointer database of private addresses. This is the most up-to-date listing of private households and is made available to the Northern Ireland Statistics and Research Agency for research purposes. People living in institutions (though not in private households in such institutions) are excluded. A total of 2,200 addresses are selected for interview.
The Pointer database provides a good sampling frame of addresses, but contains no information about the number of people living at an address. Further selection stages were therefore required to convert the listing of addresses to a listing of individuals from which one person (the ‘selected respondent’) is chosen to complete the questionnaire.
The interviewers list all members of the household who are eligible for inclusion in the sample: that is, all persons currently aged 16 or over living at the address. From this listing of eligible adults, the interviewer's computer randomly selects one adult. This person, the selected respondent, is then asked to complete the interview.
There are two parts to the questionnaire:
- The household section - This is the core element which will remain the same from survey to survey.
- The selected respondent section - This is the variable element which will change from survey to survey depending on client needs
The core information for each survey includes:
- Age and tenure of accommodation
- Household composition (i.e. household grid)
These are to be asked of a responsible adult. The selected respondent completes the clients’ modules. We also collect details of employment, education, religion, ethnicity, sexual orientation and income from the selected respondent.
