 So what have been the basic departure point for the discussion around poverty and growth in the working group you've been involved with here now? The starting point I think is the good growth performance which Africa has experienced over the last 15 years, 10 years maybe particularly, which is very much a reversal. We remember the 1980s, we remember the first half of the 1990s when Africa was the part of the world that was doing really badly. In the last 10 to 15 years Africa has been performing much better, the growth rates have been much better. What we don't know enough about is how that translates into better living conditions for the people that live in Africa, to what extent has that growth been associated with poverty reduction, or have the benefits of this growth gone to multinational companies and rich people and not accrued to the ordinary people in Africa? So what's the difference of being poor in a developed country and in a middle income country? I think it's a sort of scale of poverty. In very poor countries in Africa people can struggle to feed themselves so it's really quite basic things. It's obviously very poor living conditions, it's obviously been very exposed to ill health and often not able to protect yourself, not able to consult, not able to afford medicines and just not being able to afford to eat adequately either, to be adequately nourished in some cases. So I think it's a more extreme case. Being poor in any society is difficult but I think it's especially difficult in a low income environment like much of Africa. So what is it that you know that you don't know about poverty and growth in Africa? I think the information we know about poverty is much better than it was. There's been a lot of surveys over the last 20 years. This is partly linked to policy initiatives about poverty reduction strategies, about millennium development goals. We're better at collecting information that we were in most countries but it's not true in all countries and some of the countries which have actually been growing strongest are probably the ones that we know least about like Angola, like Sudan, these are countries which have grown well and we have virtually no information. Even Nigeria, the biggest country in Africa, we don't really have a consistent story about what's happening to poverty. But in general the picture is better in terms of what we know about poverty. And I think the message, I mean there isn't a general message because Africa is made up of many different countries. But I think there's quite a few cases of positive experiences of poverty reduction, falling infant mortality, better access to health care. I think there are positive messages but it's not everywhere. If you talk about monitoring growth and poverty, what sort of tools instruments should be developed? Okay, well in monitoring growth, I mean countries measure their national income, their gross domestic product as it's called. Actually, I mean there are some questions about the reliability of this because a lot of the economic activity is actually quite informal and it's difficult to pick up. Even subsistence agriculture is difficult to monitor accurately. But we can get a sense of what is happening in terms of growth. In terms of poverty, this is typically done by surveys, so interviewing a sample of the population, finding out what's their income or consumption, finding out what's their experience of using health care, finding out to what extent they have had children who died young, finding out if their kids are going to school and things like that. These are the sort of things that we typically do based on a sample of the population and if we choose the sample appropriately, we can say something about the whole population based on that. Thank you very much.
