The UN World Population Outlook 2022 report predicts that the global population will reach 8 billion by the 15th of this month. This number will continue to grow in the coming decades, but the growth rate will slow down and there are regional differences.

Agence France Presse reported on the 7th, citing the data of the United Nations Population Division, that the global population in 1950 was 2.5 billion, reaching 8 billion means more than doubling.

Due to the increase of life expectancy and childbearing age population, the United Nations predicts that the global population will grow to about 8.5 billion by 2030, reach 9.7 billion by 2050, and reach a peak of about 10.4 billion in the 1980s, and maintain this level until 2100.

  From 7 billion to 8 billion, how long did it take?

11 years. According to the previous statistics of the United Nations Population Fund, the global population reached 7 billion on October 31, 2011. It took 11 years and a half months for the world population to grow from 7 billion to 8 billion today.

  How many people will there be in the world at most?

About 10.4 billion yuan. According to the latest prediction of the United Nations, by the 1980s, the global population will reach a peak of about 10.4 billion, and maintain this level until 2100.

However, the data given by different research institutions are also different. For example, a study by the Institute of Health Indicators and Assessment of the University of Washington in the United States in 2020 shows that the global population will peak in 2064, but will not reach 10 billion, and will decrease to 8.8 billion in 2100.

  Now, where is the world's largest population?

Asia. In 2022, the two regions with the largest population will be distributed in Asia: East Asia and Southeast Asia have 2.3 billion people (about 29% of the global population), and Central Asia and South Asia have 2.1 billion people (about 26% of the global population).

  India's population will surpass China's?

Soon. China and India each have more than 1.4 billion people, accounting for the majority of the population of the two regions. India is expected to become the most populous country in 2023 at the earliest, and reach about 1.67 billion in 2050.

  Where is the new population more?

The United Nations predicts that by 2050, more than half of the world's new population will be concentrated in eight countries, including the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.

  Will the population continue to grow?

Yes, but the growth rate is slowing down. The growth rate of the world population during 1962-1965 was 2.1% per year. Since then, the growth rate has dropped sharply and will be less than 1% in 2020. By 2050, the annual growth rate of global population may drop to about 0.5%.

In addition, in 2021, the average fertility rate of the global population will be 2.3, that is, every woman will have 2.3 children in her lifetime. In 1950, the fertility rate will be 5, and it is expected to drop to 2.1 in 2050.

  How long do people live?

The global average life expectancy continues to increase. In 2019, the global average life expectancy was 72.8 years, 9 years more than in 1990; By 2050, the average life expectancy is expected to reach 77.2 years.

However, the combination of increasing life expectancy and declining fertility will intensify the aging of the population. The proportion of people over 65 years old in the total population will be 10% in 2022 and will rise to 16% by 2050.

  What does the UN say?

In "Eight Billion People, One Human Being", UN Secretary General Guterres said that while the human family is growing, it is also facing increasing inequality. If these problems are not resolved, the world will be full of tension and mistrust, crises and conflicts.

He also quoted Mahatma Gandhi as saying, "The things in the world are enough to meet everyone's needs - but not enough to meet everyone's greed.
