One study tells us when the world’s population, which has been growing for centuries, will begin to decline. This has been exposed in the Lancet’s new report. In which it is estimated when this will happen. Well, this is going to start in this century.
Currently the world population is believed to be 7.8 billion. The world population will rise to 9.7 billion by 2064, but after that it will begin to decline, the report said. By 2100, the world’s population will shrink to 8.79 billion.
There are still 53 years until the end of 2064, but it is certain that this will be the time when the world population will have the highest point. Then there will be many reasons for the declining population. These include low birth rates and an aging majority population. It will happen in at least 23 countries, including Japan, Thailand, Spain, Portugal, South Korea and other countries, and will reduce its population by up to 50 percent.
How much will China’s population decline?
China is currently the most populous country. The population, which was 1.4 billion in 2017, will halve by 2100 to 732 million.
More in some countries
While the report says that in some countries the population will decrease and the effect will be on the world population, the population will increase in some places like North Africa, the Middle East and Sahara Africa. The population here could increase from the current 1.03 billion to 3.07 billion.

How much the population in India will decrease
The study also says that the population in India will start to decline. At present it is close to 1.4 billion, which will drop to 1.09 billion by 2100. The world’s population declined in the 14th century. The reason for that is plague. The study was led by Stan Emile Walcett, a professor of global health at the Institute for Health Metrics and Evaluation. He says if our prediction is correct, the reason for the declining population will be low fertility. No infection.
Why does this happen
If further progress is made in female education, contraceptive methods will increase and this will reduce both fertility and population, the report said. The fertility rate was 2.37 in 2017 and will be 1.6 in 2100.

Weather can also play a role
World-renowned scientist Michio Kaku writes about this in his book “Physics of the Future – Discoveries That Will Change Our Lives”. According to meteorologists, the weather will change by 2030 and it will wreak havoc on the human race, he wrote. The heat will start to increase. Lack of water causes a lack of oxygen in the air. It is estimated that our population may decline to one billion. Although some other scientists disagree, they say the population will stop because the growth rate is lower than the season.
There are many reasons for the declining population. Of these, fertility rates, better female education, etc. raise awareness about contraception and hit the weather. (Shutterstock)
Humans are susceptible to disease
We do most of the work with machines, and as global warming and alienation from nature, more and more new diseases disappear. The machines call us to relax, because of which the strength in our muscles runs out and we become weak. Of course, the development of medical technology and antibiotics can have very negative effects on the body’s defense system.
How life and the world will change after the 60s
Renowned scientist Michio Gaku says in his book “Physics of the Future – Discoveries That Will Change Our Lives” that “planning to create colonies on other planets and in space will begin”. A new solar planet may also be discovered. However, space flights will become more common. As the countdown to the depletion of natural energy resources begins, efforts will be made to find alternatives to the sun’s radiation or to other planets in space. A new forum will be created between all countries on this. The population will decrease instead of increase. This may be due to the fact that the growth rate is lower and the reproductive power is lower due to the dependence on machines and the internet based life. Failed attempts to preserve old traditions will continue. Old lifestyles and developments can be turned into museum objects. “
