The highest increase in new births in the world between now and 2050 is expected to occur in Nigeria. By 2050, Nigeria's population is projected by the United Nations to be 389 million, rivalling that of the United States at 403 million. By the end of the century, the U.N. projects that Nigeria's population would be between 900 million and 1 billion, nearing that of China which would by then be the second most populous country in the world after India. The reason for this is because while Nigeria's population would continue to grow geometrically, China's population is expected to begin to shrink by 2030.
Today, Africa has the youngest population in the world. 200 million Africans are between 15 and 24 years old. This young population is expected to more than double by 2050, when as many as 800 million Africans are expected to be between the ages of 25 and 59. This is expected to provoke a dramatic shift in the working population of the world. Today, China has the advantage of having the largest labour force worldwide. But soon, China will be replaced by Africa. According to these projections, by 2050, one out of every four workers in the world is likely to be an African. This African labour force would be young and relatively cheap. Therefore, it is to be expected that multinational companies of the West looking for cheap labour would be inclined to move their businesses to Africa, instead of East Asia.
