 So the idea is to take a group of African countries, South Africa, Mozambique, Ethiopia, Ghana, Nigeria and Kenya and collectively take those six countries and try and understand the relationship between growth and employment and overlay that with demographic challenges. In particular, what we've tried to do across the chapters is to explain sectoral transformation or structural transformation at the sectoral level in terms of percentages of GDP and so on, the relationship between that transformation and its employment outcome. So in that context, what we're hoping to do is provide a much clearer and tighter relationship and an understanding of the relationship between sectoral patterns of growth in these African economies and their respective employment outcomes. That's partly what the chapters try and do is to make the link between demographic dividends which incidentally are not evenly spread across the economies. Some economies do not have a demographic dividend like South Africa. Others drive the overall African demographic dividend like Nigeria and so the idea then is to link this notion of a demographic dividend to the jobs challenge that on the one hand you can see this as a boom for foreign retailers who see this as an untapped consumer market but of course consumers need jobs and I think that's the link we try and make in the chapters. So what we've done in this context is of course drawn on the wonderful sort of support network and infrastructure as well as resources from UNU wider but then also partnered with the Africa Growth Institute at Brookings. The outputs will reflect this collaboration in that we'll have a working paper series both on the UNU wider side as well as Brookings working paper series respective to the African economies that we're studying and then finally a Brookings publisher book that we'll edit under the guidance of the UNU wider director Fintop and myself.
