According to United Nations’ estimations, we are waiting for a population of 9.8 billion people in 2050.
The countries weighing more in the growth of the demographic curve are the least developed ones, where population growth is increasing more than elsewhere.
And the countries ranking first are all African! Burundi, Malawi, Niger, Nigeria, Somalia, Uganda, Tanzania, Kenya, Zambia… all countries where a fivefold increase of the inhabitants has been predicted.
In 1900, Africa had 100 million inhabitants, against a world’s population of 1 billion people.
One hundred years later, in 2000, people on the continent were 700 million. In one hundred years, they will be 4.3 billion.
This growth, together with a longer life expectancy – which will pass the threshold of 60 years old –, a decreasing infant mortality rate – which is going to achieve almost zero –, and a strong youth element which is having children – today half of African population is less than 15 years old and its fertility rate is of 5.5 children for each couple – will form a new critical mass of people asking for their own space in the world.
And we are talking about food, houses, medical assistance, employment, retirements, infrastructure and personal services.
If Africa is not ready to satisfy these needs, the youngest will move away. They will emigrate.
Towards the continent’s 54 countries or abroad. Towards Europe, for example.
