Free teaching material for a fact-based worldview RELATED QUESTIONS In this short video Professor Hans Rosling shows how the drop in number of babies per woman is distributed across the world. The numbers have dropped in all regions of the world, but not exactly in the same way and not at the same time. The drop in Africa and Asia came later, but is faster than in the Americas and Europe. If the current trend continues, by the end of the century we can expect two babies per woman all over the world. Short answer — It dropped everywhere How did babies per woman change in different regions? Short answer — more adults Why is population growing even if babies per woman dropped? The future fast growth is not due to the same reasons as the fast growth historically. In the future, people will indeed survive longer, but life expectancy is only going to increase a little bit. And the number of children in the world is expected to remain stable. The main reason for the future fast growth is the highly predictable fill-up of adults, as larger young generations grow older as explained in another slideshow. Short answer — first slowly. Then fast. How did the world population change? In this short video Professor Hans Rosling shows how the size of the world population has changed over time. From the beginning of agriculture to the industrial revolution the population growth was very slow. Then the population started to grow rapidly because fewer died young. Today, most women have fewer children and therefore the rapid growth will soon be slowing down. World population will most likely stabilise around 11 billion towards the end of the century. www.gapminder.org/teach Version: 1 Free teaching material for a fact-based worldview
