By 2050 around 2.2 billion people could be added to the global population and more than half of that growth will occur in Africa.
Africa will account for the highest population spurt with an additional 1.3 billion people on the continent, a new UN population report shows.
Much of Africa’s population boom will come from Nigeria, currently the world’s 7th most populous country. By 2050, the report predicts, Nigeria will become the world’s third largest country by population, becoming one of the six nations projected to have a population of over 300 million.
