Japan's estimated child population has hit a record low after falling for 40 straight years, government data showed Tuesday, providing further evidence of the country's aging population.

The number of children age 14 or younger stood at 14.93 million as of April 1, some 190,000 fewer than a year before and the lowest figure among comparable data available since 1950, according to the Ministry of Internal Affairs and Communications.

The proportion of children within the overall population also fell to its lowest point — 11.9% — after 47 straight years of decline.

Japan has the lowest such ratio among the 33 countries with a population of over 40 million, below South Korea's 12.2% and Italy's 13.3%, according to the U.N. Demographic Yearbook.

The ministry said there were 7.65 million boys and 7.28 million girls.

Children age up to 2 accounted for 2.65 million of the total, relatively lower than other age brackets and reflecting a decline in the number of births, the ministry said.

The child population in Japan peaked in 1954 at 29.89 million. It briefly picked up around the early 1970s but has continued to fall since 1982.
