I think Sylvie answered that as well. Because poverty is so complex and there are so many diverse needs of the population, it's difficult to have one measure that would address all the issues. There are the advantages of the various suites that we talked about. We want to do trends, and the LICO is the best in terms of monitoring that. There are international comparisons, LIM, and the market basket measure, which gets at the regional differences.
There are also benefits to looking at it from a holistic point of view. Those three measures focus on income, and our European colleagues are looking at material deprivation, which Sylvie also highlighted. It gets at the quality of life and one's interactions and involvement in society.
For those reasons, I think most countries have not adopted an official poverty measure.
