China’s population is aging due to its one child policy. Europe is aging and will face huge problems funding social programs due to low birth rates.
Even India, which is expected to have the world’s largest population soon, has a lower birthrate than Africa.
In a few decades, Africa as a whole will have the largest population according to the World Bank.
