Dr. Claire Keane:

It is much more difficult. We can track who is getting what in respect of income. We can follow what income men get. Even in the example I gave we can see who is getting different earnings and benefits but what we cannot see is how exactly they are spending that. Therefore, even if we have information on what the household is spending it is very difficult to break that down into who is actually paying for it. Perhaps Mr. Roantree might want to comment.
