Mr. Pádraig Dalton:

It varies from survey to survey. Generally, the CSO does not pay anyone for providing information to fulfil our legal obligations. For example, the survey on living conditions can take up to an hour to complete. The QNHS can take up to 20 or 25 minutes to complete. The most difficult survey we currently carry out is the household budget survey, and we make a small contribution to households because they keep a diary for us for about two weeks and record information on every item of expenditure which, of course, we subsequently use to weight the CPI, which is critical for all of us.
