What is the population of Africa
The population distribution of Africa is strongly influenced by climatic conditions and the agricultural usability of the regions. Therefore, the population density in Africa is only in some regions that can be used well for agriculture, over 200 inhabitants per km2. The large desert region of the Sahara, however, is almost uninhabited, as the people cannot farm here. The long periods of drought, during which people in the Sahara can hardly find any drinking water, make life difficult for the few nomads who live in this region. Most people therefore moved to more fertile regions along the Nile or to the coastal areas, which have a more favorable climate.
The population in Africa is growing rapidly. Africa has the highest growth rates worldwide. The population has increased almost fivefold since 1950, bringing Africa to almost a billion people in 2010. Around 6.8 billion people currently live around the world. The population of Africa therefore makes up almost 15 percent of the world's population. That the population in Africa is growing so fast is due to the high birth rate, that is, because many women have a lot of children. In many families, children are seen as "retirement plans". They are supposed to look after and care for their parents later when they are old and sick. Often, however, men and women in developing countries are not informed about contraception options.
Urban growth in Africa, as in most developing countries, is very high. Cairo, the largest city in North Africa, now has a population of over ten million. In 1950, however, there were only a little over two million inhabitants. And many other cities, such as Lagos, Dakar or Addis Ababa, are also growing very rapidly. Urbanization is increasing all over the world, but in many developing countries this process is very rapid and to a very great extent. Due to the rapidly growing population, many cities are swelling into megacities. However, many people also migrate to the cities from rural regions in the hope of being able to lead a better life here. This rural-urban flight is often triggered by the extreme poverty of the people in rural areas and increases the population pressure in the cities. Most of the time, however, the infrastructure, such as water supply and disposal, schools and hospitals, is not designed for that many residents. Many immigrants therefore live in slums under very poor conditions.
HIV / AIDS
Because of poor medical care and because many people are not informed about the disease and how to protect it against HIV, many people in Africa become infected with HIV / AIDS and die. The countries south of the Sahara are worst hit. Botswana, for example, is one of the countries with one of the highest infection rates in the world. The two population pyramids show that in Botswana, the high infection rate and the resulting high death rate will likely result in the population dropping by more than half a million between 2005 and 2025. Women and men over 40 years of age will then only make up about 15 percent of the total population.
Many other countries in southern Africa also have high infection rates and a large number of AIDS deaths. Unlike in Botswana, however, the birth rates there are so high that the total population is still growing.
