The study is based on modern analytical tools and population databases such as birth rates, mortality rates and migration status from countries. According to the study, by 2100, the world population will be about 2 billion more than the forecast of previous studies and close to the 10.9 billion projected by the United Nations in 2013. .

Most population growth occurs in Africa with the population here expected to increase from the current 1 billion to 4 billion by the end of the century. The main reason is the high population in the South Sahara region has a high birth rate.

Many researchers are concerned, with such a dizzying population growth rate, the Earth will become overloaded, natural resources are exhausted, food and food are scarce while epidemics increase. In order to ensure long-term benefits, Africa needs to implement a policy of reducing birth rates by enabling people to have more access to contraceptives and to enhance awareness-raising education for women. female.

Research shows that the population in other regions of the world will be less volatile. Specifically, the population of Asia increased from 4.4 billion today to 5 billion by 2050 before tending to decrease. Population in North America, Europe, Latin America and Caribbean remained below 1 billion.
