By 2100, 40% of the world will be African

In 2100, it is estimated that 40% of the world will consist of Africans. UNICEF tells us that over the next 35 years, another 1.8 billion Africans will be born. When we reach the end of this century, there will be 4.2 billion Africans.

Meanwhile, it's estimated that the total Asian populations will stabilize at around 5 billion throughout this century, and by 2100, 80% of the world will be Asian and African.

Where do Europeans fit in this picture?

As the above graph indicates, the sub-Saharan African population has outgrown the European population beginning this century. Between 2040 and 2050, the Middle East will catch up. And this is not taking in account the already existing populations of non-European origin in Europe itself.

The total European populations of Europe and all former colonies combined is roughly 800 million people. This number keeps on falling due to low fertility and birthrates among Europeans and their descendants. Meanwhile, the population of Africa is already at 1.2 billion and Asia at 4.4 billion.

The source of the African population growth is largely due to foreign aid. Conditions in Africa are barely improving and corruption stays at all time highs. Fundamental agriculture and infrastructure simple isn't being built in amounts to keep up with the population growth. What will happen if foreign aid would stop?
