UN experts conducted a study, according to the results whose previous calculations increase the population of our planet turned out to be inaccurate. Scientists have found that by 2100 on Earth about 11 billion people will live, which is two billion more than previously thought. Researchers from Washington universities received the latest statistics from the UN for year 2014. Having processed the information provided, scientists suggested that with 80% probability the population of our planet grow from 7.2 billion to 9.6-12.3 billion by the end of the current century. Note that before this, experts who are involved demographic situation in the world, it was believed that by the 1990s, as soon as the population reaches nine billion people, the number of inhabitants of the planet is stabilizing or even starting to shrink. However, as time has shown, they were mistaken. At this moment it is believed that in the future the greatest increase will be in Africa: its population will quadruple from one to four billions. The fact is that, contrary to the forecasts of demographers, fertility on the continent is not falling. Moreover, African families remain large: they have an average of four children. It’s in mainly due to lack of contraceptives, reports Science Edition. The population growth can also be explained by the fact that on continent has reduced mortality from HIV. Note that, according to forecasts of demographers, the situation on other continents will be more stable. And Asia will have a peak of growth in 2050, then it the population will be five billion, and after that the increase in the number residents will decline and the population will begin to decline. Number North Americans, as well as Europe and Latin America, will be less than a billion, experts predict. Commenting on new data, a UN spokesman emphasized that the forecasts published previously, based on certain development models, therefore not could give an accurate forecast for 100 years in advance. “Our study more reasonable, and we represent the confidence interval, which may be useful for developing practical measures, ” Said Patrick Gerland, a UN demographer.
