Where do Black people enjoy the best quality of life in the world?

  I would like to know if there has been a study of per capita income, education, healthcare, government or other leadership occupations for people of African descent in the world.  Recently, in the course of my personal DNA exploration, I discovered my L3b Haplo group emanates from the region of Eastern Africa.  We now know that Africa is anthroplogically and archaeologically the cradle of humanity.  Yet worldwide, the peoples of this descent seem to have been electronically and economically left back.

  I think that this query would be an interesting topic for research and report.
