The Living Costs and Food Survey is a very important survey as it is the main source of information on the cost of living in Northern Ireland, which is needed to calculate the rate of inflation. It is also a valuable source of information on health and nutrition.
If you have received a letter, then your address has been selected at random from a list of all addresses in Northern Ireland. One of our interviewers will be calling to ask you to take part and to explain the survey in more detail. All our interviewers carry an official identification card, which includes their photograph and a NISRA logo as it appears at the top of this webpage.
It is important to the success of the survey that you take part, as we need information from everyone selected to make sure the survey is completely representative of Northern Ireland households. As the survey is so important, each person aged 16 and over who takes part will receive a £20 High Street voucher and each child aged between 7 and 15 will receive £5.
Everything you tell us is treated in confidence. The results will not be used in any way in which they can be associated with you or your address.

The LCF is a voluntary sample survey of private households. The basic unit of the survey is the household. A household comprises 1 person living alone or a group of people (not necessarily related, living at the same address) who share cooking facilities AND share a living room or sitting room or dining area.
The survey is continuous, interviews being spread evenly over the year to ensure that seasonal effects are covered.
Each individual aged 16 and over in the household visited is asked to keep diary records of daily expenditure for 2 weeks. Information about regular expenditure, such as rent and mortgage payments, is obtained from a household interview along with retrospective information on certain large, infrequent expenditures such as those on vehicles. Children aged 7 to 15 are asked to keep a simplified version of the diary.
Detailed questions are asked about the income of each adult member of the household. In addition, personal information such as age, sex and marital status is recorded for each household member.
