2018 World Population Data Sheet is now available

The Population Reference Bureau has recently published its annual Data Sheet with a focus on changing age structures around the world and resulting consequences for policy-making and development. This publication provides the latest data on key population, health and environment indicators for the world, regions and more than 200 countries.

The key findings include:

  • The world population will reach 9.9 billion in 2050, up 29 percent or 2.3 billion from an estimated 7.6 billion now.
  • Africa’s population will more than double by 2050 to 2.6 billion and the continent will account for 58 percent of the global population increase between 2018 and 2050.
  • By 2050, the number of people in Asia will rise about 717 million to 5.3 billion, while Europe (including Russia) will see a decline in population from 746 million to 730 million. The population in the Americas is seen increasing to 1.2 billion from 1 billion now.
  • The population of 26 countries, nearly all in Africa, will at least double by 2050. The population of Niger in West Africa will nearly triple.
  • The population of 38 countries will be smaller in 2050 than in 2018. The biggest numerical decrease will be in China (about 50 million) and the biggest percentage decrease in Romania (around 22 percent).
  • The 2018 worldwide total fertility rate (TFR) is 2.4. The global TFR has been declining but remains high enough to drive continued global population growth. Niger has the highest TFR at 7.2; South Korea the lowest at 1.1.
  • As the global population increases, continued declines in fertility and mortality mean that the world population’s shift toward an older age structure (known as population aging) will accelerate. The 2018 World Population Data Sheet can be found here
