The average population growth rate in Africa is the highest. What is the main reason?

Analysis: Africa's high population growth rate also benefits from the reduction of mortality rate, especially the child mortality rate, which has dropped significantly in the past 15 years. According to an important new population study, the greater development of African economy in the next few years may make Africa's population growth rate exceed the previous forecast.

According to the estimation of the United Nations, the population of sub-Saharan Africa will double by 2050, which may add more than 654.38 billion people to the world. The results of this new study show that the next population growth in Africa may be even higher. It is generally believed that with the development of economy and the improvement of education level, people, especially women, will want to have fewer children.

Resident population:

By the end of 2002 1 and1,the population of Africa was about 1.286 billion, and the world population was 7.585 billion, ranking second in the world after Asia. The average annual population growth rate in Africa is 2.3%, much higher than that in Asia (1%), and the population growth rate in sub-Saharan Africa is higher than that in North Africa. There are many poor people, which are expected to reach 2 billion by 2050.

Africa's birth rate, mortality rate and growth rate are among the highest in the world. The population distribution is extremely unbalanced, with about 65,438+0,000 people per square kilometer along the Nile and the Delta. Sahara, Namib, Kalahadi and other deserts and some arid grasslands and semi-desert areas are less than 1 person per square kilometer. There are also large areas of no man's land.
