The Dhaka Times Desk This new research has revealed that the world's population will reach 9.7 billion by 2064. Then it will gradually reach 880 million by the end of the current century.
Now the question is, on what basis did the researchers make such a prediction? The researchers reasoned that the population would decline as women became more educated and used contraception.
183 out of 195 countries in the world will no longer have the birth rate needed to grow the population at the current rate (2.1 per woman capacity) by the beginning of 2100. Researchers from the Washington School of Medicine's Institute for Health Metrics and Evaluation have provided this information.
At least 23 countries, including Japan, Thailand, Italy and Spain, will see their populations drop by about 50 percent, the researchers said. However, in sub-Saharan Africa this population will triple and by the end of the current century half of the world's population will be on the African continent.
A recent study published in the Lancet journal also said that some countries, including India and China, will see a dramatic decline in the working population, which will severely hamper economic growth. Also there will be negative impact on labor force and social cooperation system. Death rates will decrease and life expectancy will increase, so that by 2100 there will be at least 237 million people over the age of 65, while there will be 1.7 billion people under the age of 20. People over 80 will increase 6-fold from 141 million to 866 million. And the number of children under 5 will decrease by 40 percent to 401 million.
Researchers say that even if the birth rate falls, immigration will balance the population decline. Especially, countries like USA, Australia and Canada.
Dr. leading the research. Christopher Murray said, 'Since 1960, the so-called population explosion has been happening in the world. But soon we will see a tipping point, when the population will begin to go from very high to very low through a great transition.'
In a report from the 'Global Burden of Disease Study 2017', researchers say that the population will shrink the most in Asia and Eastern and Central Europe. According to the author of the paper, Japan's population was 128 million in 2017, which will decrease to 60 million in 2100. Thailand will decrease from 71 million to 35 million, Spain will decrease from 46 million to 23 million, Italy will decrease from 61 million to 31 million, and Portugal will decrease from 11 million to 5 million and South Korea will decrease from 53 million to 27 million. . Total population of 34 countries including China will decrease by half.
Dr. leading the research. According to Christopher Murray, not only will the population decline, but society in general will age, which will also affect economic growth. He also said, 'The number of people taking help from the government will increase; That means the number of social security and health insurance will also increase. Although the people paying taxes will also decrease.
On the other hand, there were 103 million people in the sub-Saharan region in 2017, by the year 2100 it will increase to 307 million! The population of North Africa and the Middle East is projected to increase from 600 million to 978 million.
At the moment the population of the world is 779 crore 81 lakh. Out of this, the highest 143 crore is in China, the second highest is 138 crore in India. Bangladesh is in eighth place with a population of 16.47 million.
