The world’s population is projected to hit an estimated eight billion people on Tuesday, according to the United Nations, with much of the growth coming from developing nations in Africa.
Among them is Nigeria and over the next three decades the West African nation’s population is expected to soar even more: from 216 million this year to 375 million, the UN says.
That will make Nigeria the fourth-most populous country in the world after India, China and the United States.
