In these complex and challenging times, accurate data is more important than ever.

Access the latest world population data and explore how it’s shaping our world.

 
 

In 2020, the world’s 7.8 billion inhabitants grappled with the novel coronavirus and the disease it causes, COVID-19, and gained new insight into the contributions of population density in urban areas, household size, and population aging to our vulnerability to pandemics. Population growth and aging will both affect our resilience in the face of future crises. Looking ahead, the United States’ population is projected to increase between 2020 and 2050, but at a much slower pace than recent decades. China’s population is projected to decrease by 2050. In contrast, many countries in sub-Saharan Africa—such as the Democratic Republic of the Congo and Mali—and some in Asia continue to experience rapid population growth and high fertility rates. The population of 25 countries is expected to at least double between 2020 and 2050.

 

For more than 50 years, PRB’s World Population Data Sheet has been one of the most trusted sources for vital demographic data used by government leaders, policymakers, researchers, academics, and decisionmakers around the world. It offers the latest population, health, and environment indicators for more than 200 countries and territories, each carefully researched and vetted by PRB’s expert team of demographers and analysts.

The 2020 Data Sheet identifies key demographic findings around the world, including:

  • The world population is projected to reach 9.9 billion by 2050, an increase of more than 25% from the current 2020 population of 7.8 billion.
  • Total fertility rates are below the replacement level of 2.1 births per woman in 91 countries and territories, mostly in Asia and Europe, as well as in the United States.
  • Western Europe and Southern Europe have the largest shares of people ages 65 years and older (21%), while sub-Saharan Africa has the smallest share (3%).
  • The population of 25 countries is expected to at least double between 2020 and 2050. Angola, Benin, and Niger are projected see a population increase of 150% or more.
  • In 12 countries and territories, at least 50% of the population lives in cities of 1 million or more residents, including the Republic of the Congo (63%), Australia (62%), and Israel (61%).
