The breakdown by education level is especially interesting: It shows that our world will be inhabited by more and more educated people. The projection shows that the number of people with no education will decrease continuously and that by the end of this century virtually all people in the world will have received some level of education (…) By 2050, only five countries are predicted to have a rate of no education above 20%: these are Burkina Faso, Ethiopia, Guinea, Mali and Niger. There is also expected to be a large increase in the numbers of people obtaining degrees, while more people complete secondary school.
