As of 2019, the total population of Africa is estimated at 1.3 billion, representing 16 percent of the world's population. [13] According to UN estimates, the population of Africa may reach 2.49 billion by 2050 (about 26% of the world's total) and 4.28 billion by 2100 (about 39% of the world's total). [13]
Of the additional 1.9 billion people projected between 2020 and 2050, 1.2 billion will be added in Africa, 0.7 billion in Asia and zero in the rest of the world. Africa's share of global population is projected to grow from 17% in 2020 to 25% in 2050 and 38% by 2100, while the share of Asia will fall from 60% in 2020 to 55% in 2050 and 45% in 2100.

The predicted urban population growth is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia. [5] Notably, the United Nations has also recently projected that nearly all global population growth from 2017 to 2030 will be by cities, with about 1.1 billion new urbanites over the next 10 years.

In sub-Saharan Africa in 1960 "only one city, Johannesburg, had a population of one million;...in 2009, there were fifty-two cities with such large populations." [ 2 ] The Nigerian city of Lagos that in 1963 had 665,000 inhabitants (Rakodi, 1997) and 8.7 million in 2000 is expected to become the world's 11th biggest city by 2015 with 16 million ...
The World Population Prospects predicts that by 2050, Nigeria will become the third most populated country in the world. Over the last 50 years, Nigeria's urban population has grown at an average annual growth rate of more than 6.5% without commensurate increases in social amenities and infrastructure."
The Population Division of the United Nations Department of Economic and Social Affairs at that time predicted the urban population would occupy 68% of the world population by 2050, with 90% of that growth coming from Africa and Asia.
