I don't really feel as though I can necessarily speak to the measurement. That would be more for an economist or a statistician, but certainly LICOs are widely used, and I don't see any reason why that couldn't be adopted as a national poverty line, although I know there are critiques of that. As I said, I'm not really in the best position to comment on those.
