Child Poverty Bill

The dilemma is that for the vast bulk of the nation's children, living standards can be assessed using household surveys on a common standard, internationally defined and all the rest of it. Is my hon. Friend's argument that, if it is not possible to put children in the groups he refers to on to that same metric—that is the key problem; we know where they are and we could survey them, but converting their living standards into the same metric is very difficult—could we not apply a rational approach to the vast majority of children; or would my hon. Friend's approach preclude us from doing that at all because it is discriminatory?
