Experts from the UN conducted a study, according to the results of previous calculations which increase the population of our planet proved to be inaccurate. Researchers found that by 2100 the world will live about 11 billion people, two billion more than previously estimated.

Researchers from the University of Washington received the latest statistics from the United Nations for 2014 . After processing the information provided, scientists have suggested that a 80% probability of the planet’s population will grow from 7.2 billion to 9,6-12,3 billion by the end of this century.

Note that before the experts who deal with the demographic situation in the world, believed that by the 1990s, as soon as the population of nine billion people, the number of inhabitants of the world will stabilize or even start to decline. However, as time has shown, they were wrong.

At the moment, it is believed that in the future will be the largest increase in the Africa: its population increased fourfold, from one to four billion. The fact is that, contrary to demographic projections, the birth rate in the continent is not falling. Moreover, African families are still many children they have an average of four children. This is mainly due to the lack of contraceptives, according to the publication Science. Also, population growth can be explained by the fact that the continent was reduced mortality from HIV.

It should be noted that, according to demographic projections, the situation in other continents will be more stable. A peak rising Asia will be in 2050, when its population will be five billion , and then increase the number of inhabitants will decline and the population will begin to decline. The population of North America, as well as Europe and Latin America, will be less than a billion, experts predict.

Commenting on the new data, a UN spokesman said that the forecasts published earlier, based on the specific models of development, so they could not give an accurate forecast 100 years into the future. “Our study more soundly, and we present a confidence interval , which may be useful for the development of practical measures,” – said Patrick Gerland, a demographer at the UN.
