The world’s population will reach almost eleven billion by the end of the century because of soaring birth rates in Africa, according to new research.
... Researchers had expected fertility on the poorest continent where a woman will give birth to an average of 5.2 children in her lifetime, to fall more quickly than it has.
The current African population is about 1.1 billion and it is now expected to reach 4.2 billion, nearly a fourfold increase, by 2100.
Professor Adrian Raftery, of the University of Washington, said: 'The fertility decline in Africa has slowed down or stalled to a larger extent than we previously predicted, and as a result the African population will go up.'
