GLOBAL POPULATION GROWTH
Presentation by Hans Rosling in Cannes
Introduction
Hans Rosling presented how world population have been changing since 1960. He also made a prediction on how the progress will continue, if no action is taken to stop the growth in the poorest developing countries. He used colourful boxes to describe the population sizes and statistical data on progress. Each box represented one billion people.
Evolution
In 1960 there were two boxes for the developing world and one box for the industrialised western world. There was a big gap in levels of wealth between the west and the rest. While people’s goal in the western world was to get their own cars, people in developing countries dreamed of new sandals.
Since 1960 the gap between these two categories of countries has been reduced, and world population has more than doubled. If the growth continues at its current trend, the population will reach 9 billion by 2050.
Solution
According to Rosling the only way to stop this growth is by getting the poorest people out of poverty, giving them education and increasing their child survival rate. This will dramatically affect the number of children per woman.
The most developed poor countries have gotten closer to the western world when it comes to birth rate. However, we still have the 2 billion poor people, whose birth rate is almost six children per woman. If four of those children survive to adulthood, the population in the poorest countries will double from 2 to 4 billion in one generation.
Statistically, it is shown that birth rate is lower in wealthiest and healthiest countries where child survival rate is near 100%. As such, Rosling describes child survival as the new green. Only by investing in improving the living conditions of the poorest countries, the current trend can be stopped, and the rate of global population growth can be kept at a sustainable level.
