The United Nations has released a report on world population estimates, predicting that the world population will begin to decline within this century. It is expected to peak at around 10.3 billion in the 2080s and then gradually decline. Incidentally, Japan’s population is expected to be 77 million in 2100. Meanwhile, a study by the University of Washington predicts that due to a global decline in birth rates, the population will peak at 9.7 billion in the 2060s and fall to 8.8 billion by 2100. It seems certain that the world population will begin to decline within this century, but it is not easy to predict to what extent. (Kei)
