UN: world population to 2050 will exceed 9.8 billion people
According to the research organization, the population growth of the planet is mainly due to the 47 least developed countries.
MOSCOW, June 22. /TASS/. The Earth’s population will increase by 2050 with the current of 7.6 billion to 9.8 billion, and in 2100 will reach 11.2 billion, despite the decline in overall fertility. This is stated in the report of the UN Department of economic and social Affairs, published on Wednesday.
According to the study, the population growth of the planet is mainly due to the 47 least developed countries where the fertility rate is 4.3 children per woman. The total number of inhabitants in these States, which currently stands at one billion by 2050 will reach 1.9 billion. The population of 26 African countries over the same period doubled, according to the report.
At the current annual population growth of 83 million people, we expect that this trend will continue, even given the fact that the level of fertility (in the world) will continue to decline.The authors of the study
The drop in the total fertility rate they associate with the aging of the population. It is expected that the number of people over the age of 60 by the year 2100 will triple and will reach 3.1 billion. According to the UN 2010 and 2015, the birth rate was below replacement population in 83 countries, which account for 46% of the total population.
The decline in birth rate is observed in Africa: if in the period 2000-2005, the figure was there of 5.1 children per woman, from 2010 to 2015, it decreased to 4.7. At the same time, the population of the dark continent is gradually aging. “Although the African population will remain relatively young for several more decades, the proportion of those over 60 years will increase from the current 5% to 9% in 2050 and to about 20% by the end of the century,” the report notes.
The study also contains a forecast of growth of India’s population, it would exceed China’s population in 2024, reaching $ 1.4 billion. In addition, the UN experts believe that by 2050 the US will lose its current position as the third population of the country, giving it the place of Nigeria, which is now in seventh place.
