By around 1800, the population began to increase rapidly, starting in the rich countries and then, from the twentieth century, in the rest of the world. What are the reasons for this growth, and what factors are affecting the population today? Will the world population level off in the years to come? How will the world be populated in the future?

The European Demographic Data Sheet pools current figures as well as projections. It covers the EU 27-countries and 22 other states on the European continent as well as Japan and the United States.

The Data Sheet is updated with a new focus every two years. Maintainer/Info: Sergei Scherbov
