Geographical Location: Sub‐Sahara Africa
The sub-Saharan Africa region records the highest population growth rates worldwide. According to UN projections, the number of people in sub‐Saharan Africa is likely to double to over two billion by 2050. The high population growth is a result of the young age structure, the continuing high fertility and the increasing life expectancy. Women in sub-Saharan Africa have an average number of just under five children, with an average of six in Uganda and seven in Niger.
Almost half of the population – 42 per cent – is younger than 15 years of age. For every 100 people of working age there is an average of 84 people that need support, i.e. people that are very young and old. In Niger und Uganda, 100 employable persons even have to support approximately 105 younger or elderly people.
Over 60 per cent of the population in sub‐Saharan Africa lives in rural areas, yet with an urbanization rate of four per cent, the urban populations are growing faster than in any other region of the world. In just 40 years, the proportions between urban and rural populations might be reversed.
