TOKYO: The number of children in Japan has fallen to a new low, while the amount of people over 65 has reached a record high as the population ages and shrinks, the government said on Sunday. There were an estimated 16.33 million children aged under 15 as of April 1, down 160,000 from a year earlier, the Internal Affairs and Communications Ministry said. It was the 33rd straight annual decline and the lowest level since records began in 1950, according to the ministry. Children accounted for 12.8 percent of the population, the ministry said. In contrast, the ratio of people aged 65 or older was at a record high of 25.6 percent. Of major countries with a population of at least 40 million, Japan had the lowest ratio of children to the total population— compared with 19.5 percent for the United States and 16.4 percent for China, Jiji Press said.
