Currently, about one in seven (15%) of the world’s people live in Africa. By 2050, it will be closer to 1 in 4 (24%). Most of this growth will occur in sub-Saharan Africa, due to a current annual increase in population of 2.6%. Population growth is high because the average woman in sub-Saharan Africa has more than five children.
With reductions in overall mortality rates through improvements in sanitation, immunisation, and improved access to modern health care, death rates have dropped. Yet birth rates have remained high, resulting in high population growth, with a large proportion of children dependent upon working-age adults.
In 39 African countries, 40% or more of the population is under 15 years of age.
