578. World Population Prospects 2022: Reaching 8 Billion on November 15
The United Nations has released its World Population Prospects 2022 report on the occasion of World Population Day on July 11. The report predicts that the world population will reach 8 billion on November 15, 2022. The report states that reaching 8 billion people is both a cause for celebration and a call to find solutions to the challenges humanity will face in the future.
The key findings are as follows:
- The world’s population is projected to reach a peak of around 10.4 billion people during the 2080s and to remain at that level until 2100.
- It is expected to reach 8 billion by the end of 2022. It took about 12 years to grow from 7 to 8 billion, approximately the same time as from 6 to 7 billion. The next billion is expected to take approximately 14.5 years (2037).
- Half of the 8 billion added to the world population was a result of Asia’s demographic expansion. Africa made the second largest contribution (almost 400 million).
- Ten countries contributed to more than half of population growth leading from the 7th to the 8th billion. India was by far the largest contributor, followed by China and Nigeria. Africa and Asia will drive population growth until the 9th billion is achieved in 2037.
- Currently, two-thirds of the global population lives in a country or area where lifetime fertility is below 2.1 births per woman (also known as replacement fertility).
- Global life expectancy at birth reached 72.8 years in 2019, an improvement of almost 9 years since 1990. But in 2021, life expectancy for the least developed countries lagged 7 years behind the global average.
- In many developing countries, the share of population at working ages (between 25 and 64 years) has been increasing.
* Population replacement level: The fertility rate at which the population is stable over the long term, which is set at 2.1 in developed countries.
We have created a dashboard that shows the population trends of countries around the world.
Check out the past and future population trends of countries and regions around the world.
