The global population will reach 8 billion
According to the UN "World Population Outlook 2022" report, it is expected that by the 15th of this month, the global population will reach 8 billion. This number will continue to grow in the next few decades, but the growth rate will slow down and there are regional differences.
Agence France -Presse quoted the UN Population Division Data Newspaper on the 7th that the global population of 2.5 billion in 1950, reaching 8 billion, means more than doubled.
Due to the increase in life expectancy and childbearing age, the United Nations is expected to increase by about 8.5 billion by 2030, reaching 9.7 billion in 2050, and a peak of about 10.4 billion in the 1980s, and maintained this level to 2100 years.
However, a study of the Institute of Health Indicators and Evaluation of the University of Washington in the United States estimated that the global population will reach its peak in 2064, but it will be reduced to 8.8 billion by 2100.
The main author Stan Emir Walsett believes that his team adopts the "completely different fertility rate model" as the United Nations, and the estimated global population peak value is low, between 9 billion and 10 billion.
The United Nations predicts that by 2050, more than half of the global population will be concentrated in 8 countries in the Congo (Gold), Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.
According to Snow, the average age gap in different regions is "never as big as today." The average age of Europe is 41.7 years, while the South Africa is 17.6 years old.
Snow believes that the average age may gradually become balanced in the future, but unlike the average age of various countries in the past, in the past, the average age of various countries may be in the elderly.
According to the "World Population Outlook 2022" report, India is expected to become the first largest population in 2023, and reached 1.7 billion in 2050, although its fertility rate has been lower than the level of fertility.
