Africa has a rapidly growing population
of 500 million people, yet 75% of the continent is sparsely inhabited.
Most people still live a traditional rural
lifestyle, though many Africans move to cities in search of employment.
Most people live where water is available, in the Nile Valley, the
coasts of North and West Africa, along the Niger, in the eastern
and in South Africa.
With the highest birthrate of any continent, Africa is projected
to grow to two billion by 2050. Women in sub-Saharan Africa bear
an average of 6 children each. Life expectancy is low (Sierra Leone:
34 years, Zambia: 37 years, other countries: 4049 years) compared
to the developed countries.
The fastest growing region on earth, Africa faces the most serious
shortages of food and water.
