Explanation:
Our generation is experiencing the most profound demographic transition ever and Africa is at the center of it.
Africa’s population is rising rapidly and will most likely double its population by 2050. Depending on the source of data, Africa will soon pass 1 billion people (and it may already have) and could reach up to 2 billion people by 2050 [ I am using the UN’s 2009 World Population Prospects, which projects Africa to exceed 1.7 billion by 2050 based on sharply declining fertility rates]. This makes it the fastest growing continent and Africa’s rapid growth will also shift the global population balance.
By 2050, Africa will be home to more than 20% of the world’s population. When some of us were born in 1970, there were two Europeans for every African; by the time we may retire in 2030, there will be two Africans for every European.
Kenya mirrors Africa’s population growth. The population has doubled over the last 25 years, to about 40 million people, and rapid population growth is set to continue. Kenya’s population will grow by around 1 million per year – 3,000 people every day – over the next 40 years and will reach about 85 million by 2050.
Many think this is a big problem. There are three reasons why I am less certain that the rapid population growth in Africa, especially in Kenya, is the fundamental development challenge:
First, despite Africa’s rapid population growth and Europe’s stagnation (even decline in few countries) the old continent remains much more densely populated than Africa. If we look at Western Europe – where I come from – there are on average 170 people living on each square km. In Sub-Saharan Africa there are only 70 today. This gap will narrow in the next decades but even by 2050, Western Europe is expected to be more densely populated than Africa. I am following the population debates in Europe, especially in my (densely populated) home country Germany. I have never heard anyone argue that there are too many people in Europe.
