A recent PwC report puts Nairobi among the top "Cities of Opportunity" in Africa. CNN reports that the report, which used metrics such as  GDP growth, ease of doing business and middle class and overall population growth puts Nairobi at number 7.

On top of the list is Cairo, Egypt, followed by Tunis (Tunisia), Jo'berg (South Africa) and Casablanca (Morocco). This puts Kenya ahead of Nigeria as Lagos came at number 8. At the bottom of the list is Kampala, Uganda.

Mass Urbanization is a major factor that implies a country's positive growth. In the distant future, most of the world's population will be based in cities.
