The Population Reference Bureau’s 2016 World Population Data Sheet, released in August, offers valuable insights into not only current and projected demographic measures, but also health, energy and environment trends around the world.
The report predicts that Africa’s population will reach 2.5 billion by 2050, accounting for 54 per cent of the total world population growth. However, Asia will remain the most heavily populated region with a gain of nearly 900 million (36 per cent of global population growth), and India will replace China as the nation with the most people.
The number of people in the Americas is slated to rise by only 223 million, and Europe will experience a slight decline of 12 million.
