“The biggest change of our time?” he tweeted. “Africa’s increase from 1 to 4 billion people!” Four billion people before 2100, meaning that Africa will have a population on par with Asia.
–Africa’s population explosion will change humanity – Business Insider
The last 100 years have seen an incredible increase in the planet’s population. Some parts of the world are now seeing smaller increments of growth, and some, such as Japan, Germany, and Spain, are actually experiencing population decreases.
The continent of Africa, however, is not following this pattern. Now home to 1.2 billion (up from just 477 million in 1980), Africa is projected by the United Nations Population Division to see a slight acceleration of annual population growth in the immediate future.
By 2100, Africa will contribute 82% of total growth: 3.2 billion of the overall increase of 3.8 billion people. Under some projections, Nigeria will add more people to the world’s population by 2050 than any other country. The dynamics at play are straightforward.
