While the developed world argues over the ethics of issues like birth control and family planning, the poor continue to experience unprecedented population growth.
- From 2017 to 2050, it is expected that half of the world’s population growth will be concentrated in just nine countries: India, Nigeria, Democratic Republic of the Congo, Pakistan, Ethiopia, the United Republic of Tanzania, the United States of America, Uganda and Indonesia (ordered by their expected contribution to total growth). 1
- More than three-quarters of the world’s population lives in Africa (17 percent) and Asia (60 percent). 1
- Africa’s share of the global population is projected to reach 26 percent in 2050 and could reach 40 percent by 2100. 1
- In all plausible scenarios of future trends, Africa will play a central role in shaping the size and distribution of the world’s population over the next few decades. 1
- Indigenous peoples account for around 5 percent of the world’s population but 15 percent of people living in poverty. 2
- Amongst the 10 most populous countries in the world, Nigeria’s population, currently the seventh largest in the world, is growing the most rapidly. The population of Nigeria is projected to surpass that of the United States shortly before 2050, at which point it would become the third largest country in the world. 1
- China (1.41 billion) and India (1.34 billion) remain the two most populous countries of the world, representing 19 and 18 percent of the world’s population, respectively. In 2024, both countries are expected to have roughly 1.44 billion people.1
