Mauritius Best Among African Business Venues

The Economist has a ranking of African countries' business conditions and coincidentally today I just got a phone call from Mauritius, from the wife of Tony Hodges, a former colleague at IRIS and our houseguest a couple of years ago for a couple of weeks. His wife Sylvette and young son are constantly inviting us to go, so sooner or later, we have to make the trip [my Australian citizen brother lives on the Great Australian Bight, but he and family are currently working in Sumatra at Banda Aceh, so it would be hard to cobble that destination into our itinerary.

Unfortunately the link only shows the top and bottom countries, without Zimbabwe in the bottom ten---so I wonder how the data methodology was put together.
