Africa growing rapidly will play a central role in shaping the size and distribution of world population during XXI Century



 
Africa growing rapidly
«More than half of global population growth between now and 2050 is expected to occur in Africa. According to the UN’s medium-variant projection, the population of Africa could more than double by mid-century, increasing from 1.1 billion today to 2.4 billion in 2050, and potentially reaching 4.2 billion by 2100.
 
Rapid  population increase in Africa is anticipated even if there is a substantial reduction of fertility levels in the near future. The medium-variant projection assumes that fertility will fall from 4.9 children per women in 2005-2010 to 3.1 in 2045-2050, reaching 2.1 by 2095-2100.
 
The gap for Africa between the high and low variants of the new projections, corresponding to half a child more or less per woman compared to the medium variant, amounts to roughly 600 million people by 2050 (2.7 vs. 2.1 billion) and potentially 3.2 billion people by 2100 (6.0 vs. 2.8 billion).
 
Regardless of the uncertainty surrounding the future population of Africa, the region will play a central role in shaping the size and distribution of world population during this century.» (UN, 2013)
